Alanyl-Trna Synthetase Quality Control Prevents Global Dysregulation Of The Escherichia Coli Proteome, Paul Kelly, Nicholas Backes, Kyle Mohler, Christopher Buser, Arundhati Kavoor, Jesse Rinehart, Gregory Phillips, Michael Ibba

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Mechanisms have evolved to prevent errors in replication, transcription, and translation of genetic material, with translational errors occurring most frequently. Errors in protein synthesis can occur at two steps, during tRNA aminoacylation and ribosome decoding. Recent advances in protein mass spectrometry have indicated that previous reports of translational errors have potentially underestimated the frequency of these events, but also that the majority of translational errors occur during ribosomal decoding, suggesting that aminoacylation errors are evolutionarily less tolerated. Despite that interpretation, there is evidence that some aminoacylation errors may be regulated, and thus provide a benefit to the cell, while others …

Structural Basis Of Non-Canonical Transcriptional Regulation By The A-Bound Iron-Sulfur Protein Whib1 In M. Tuberculosis, Tao Wan, Shanren Li, Daisy Guiza Beltran, Andrew Schacht, Lu Zhang, Donald F. Becker, Limei Zhang

Department of Biochemistry: Faculty Publications

WhiB1 is amonomeric iron–sulfur cluster-containing transcription factor in the WhiB-like family that is widely distributed in actinobacteria including the notoriously persistent pathogen Mycobacterium tuberculosis (M. tuberculosis). WhiB1 plays multiple roles in regulating cell growth and responding to nitric oxide stress inM. tuberculosis, but its underlying mechanism is unclear. Here we report a 1.85 A° -resolution crystal structure of the [4Fe–4S] cluster-bound (holo- )WhiB1 in complex with the C-terminal domain of the 70-family primary sigma factor A of M. tuberculosis containing the conserved region 4 (A 4). Region 4 of the 70-family primary sigma factors is commonly used by transcription factors …

High-Throughput Nano-Scale Characterization Of Membrane Proteins Using Fluorescence-Detection Size-Exclusion Chromatography, Alex J. Vecchio, Robert M. Stroud

Department of Biochemistry: Faculty Publications

Structural biology has revealed predicting heterologous expression levels, homogeneity, and stability of a protein from its primary structure are exceedingly difficult. Membrane proteins, in particular, present numerous challenges that make obtaining milligram quantities of quality samples problematic. For structural and functional investigation of these molecules, however, this is what is required. Fluorescence size-exclusion chromatography (F-SEC), a technique where a protein of biological interest is fused to green fluorescent protein (GFP) and monitored, circumvents many bottlenecks inherent to membrane protein structural biology. In vivo expression yields, as well as in vitro homogeneity and stability, can be rapidly evaluated utilizing nanogram quantities …

Effects Of The Dihydrouracil Lesion On Dna Using 1h/31p 1d And 2d Solution Nmr, Benjamin M. Boyd

Graduate Theses/Dissertations

The effects of the dihydrouracil lesion in DNA were studied using two dimensional NMR spectroscopy. The sequence used was based off of the Drew-Dickerson Dodecamer, with the cytosine in the three position replaced by a dihydrouracil. All of the nonexchangeable proton chemical shifts, with the exception of the H2, H5’, and H5’’, of the lesioned DNA were identified using NOESY spectra and then compared to the chemical shift values of the Drew Dickerson Dodecamer. The largest differences in chemical shifts were observed in the nucleotides neighboring the lesion, both within the strand and on the opposite strand. The imino exchangeable …

High Concentrations Of Trimethylamines In Slime Glands Inhibit Skein Unraveling In Pacific Hagfish, Gaurav Jain, Marie Starksen, Kashika Singh, Christopher Hoang, Paul Yancey, Charlene Mccord, Douglas S. Fudge

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Hagfish defend themselves from fish predators by producing large volumes of gill-clogging slime when they are attacked. The slime consists of seawater and two major components that are ejected from the slime glands: mucus and threads. The threads are produced within specialized cells and packaged into intricately coiled bundles called skeins. Skeins are kept from unraveling via a protein adhesive that dissolves when the skeins are ejected from the slime glands. Previous work revealed that hagfish slime glands have high concentrations of methylamines including trimethylamine N-oxide (TMAO), trimethylglycine (betaine) and dimethylglycine (DMG); however, the function of these compounds in the …

Comparison Of Montage With Conventional Stereoscopic Seven‑Field Photographs For Assessment Of Etdrs Diabetic Retinopathy Severity, Nam V. Nguyen, Erin M. Vigil, Muhammad Hassan, Muhammad S. Halim, Sean C. Baluyot, Hugo A. Guzman, Rubbia Afridi, Diana V. Do, Yasir J. Sepah

Department of Biochemistry: Faculty Publications

Background: The ETDRS stereoscopic seven-field (7F) has been a standard imaging and grading protocol for assessment of diabetic retinopathy (DR) severity score in many clinical trials. To the best of our knowledge, the comparison between montage and stereoscopic 7F has not been reported in the literature. Therefore, the main purpose of this study is to compare agreement between montage and stereoscopic seven-field (7F) photographs in the assessment of DR severity.

Methods: Stereoscopic 7F photographs were captured from subjects with DR. Montages of monoscopic 7F images were created using Adobe Photoshop CS6 Extended©. The best quality image of each stereo pair …

Remodeling Of Chlamydomonas Metabolism Using Synthetic Inducers Results In Lipid Storage During Growth, Nishikant Wase, Boqiang Tu, Girish Kumar Rasineni, Ronald Cerny, Ryan Grove, Jiri Adamec, Paul N. Black, Concetta Dirusso

Department of Biochemistry: Faculty Publications

Microalgae accumulate lipids during stress such as that of nutrient deprivation, concomitant with cessation of growth and depletion of chloroplasts. By contrast, certain small chemical compounds selected by high-throughput screening in Chlamydomonas reinhardtii can induce lipid accumulation during growth, maintaining biomass. Comprehensive pathway analyses using proteomics, transcriptomics, and metabolomics data were acquired from Chlamydomonas cells grown in the presence of one of two structurally distinct lipid activators. WD10784 stimulates both starch and lipid accumulation, whereas WD30030-treated cells accumulate only lipids. The differences in starch accumulation are largely due to differential effects of the two compounds on substrate levels that feed …

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

We have used a transposon insertion sequencing (TIS) approach to establish the fitness landscape of the African Salmonella enterica serovar Typhimurium ST313 strain D23580, to complement our previous comparative genomic and functional transcriptomic studies. We used a genome-wide transposon library with insertions every 10 nucleotides to identify genes required for survival and growth in vitro and during infection of murine macrophages. The analysis revealed genomic regions important for fitness under two in vitro growth conditions. Overall, 724 coding genes were required for optimal growth in LB medium, and 851 coding genes were required for growth in SPI-2-inducing minimal medium. These …

Case 64: Alkalosis In A Patient With A Brain Tumor: A Link Between The Cns And Blood Ph, Dr. Kathleen Cornely

Translational Control Of Antibiotic Resistance, Anne Witzky, Rodney Tollerson Ii, Michael Ibba

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Many antibiotics available in the clinic today directly inhibit bacterial translation. Despite the past success of such drugs, their efficacy is diminishing with the spread of antibiotic resistance. Through the use of ribosomal modifications, ribosomal protection proteins, translation elongation factors and mistranslation, many pathogens are able to establish resistance to common therapeutics. However, current efforts in drug discovery are focused on overcoming these obstacles through the modification or discovery of new treatment options. Here, we provide an overview for common mechanisms of resistance to translation-targeting drugs and summarize several important breakthroughs in recent drug development.

Role Of The Drosophila Beaf Protein In Chromatin Domain Insulator And Promoter Function, Mukesh Maharjan

LSU Doctoral Dissertations

Proper folding of eukaryotic genomes is required to allow correct interactions between different parts of chromosomes. Precise and timely interactions among different parts of a chromosome allow proper functioning inside a nucleus, including gene regulation, DNA replication and DNA repair. Eukaryotic regulatory elements that facilitate folding and interactions include enhancers, promoters and insulator elements. Insulator elements and their binding proteins play an important role in regulating correct chromatin structure and function. The Drosophila melanogaster special chromatin structure (scs’) is one such insulator. The Boundary Element Associated Factor (BEAF) binds to scs’. BEAF is a 32 kDa protein that has two …

Experimental Evidence Supportive Of The Quantum Dna Model, F. Matthew Mihelic

Faculty Publications

The DNA molecule can be modeled as a quantum logic processor in which electron spin qubits are held coherently in each nucleotide in a logically and thermodynamically reversible enantiomeric symmetry, and can be coherently conducted along the pi-stacking interactions of aromatic nucleotide bases, while simultaneously being spin-filtered via the helicity of the DNA molecule. Entangled electron pairs can be separated by that spin-filtering, held coherently at biological temperatures in the topologically insulated nucleotide quantum gates, and incorporated into separate DNA strands during DNA replication. Two separate DNA strands that share quantum entangled electrons can be mitotically divided into individual cells, …

The Effects Of Eicosapentaenoic Acid (Epa) And Docosahexaenoic Acid (Dha) On Brown Adipogenesis In Stem Cell Culture, Darynne Dahlem

Animal Science Undergraduate Honors Theses

Polyunsaturated fatty acids (PUFAs), especially eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), are major maternal dietary supplements due to their positive benefits on neurological tissue growth during the first 12 weeks of gestation. Previous studies show that EPA and DHA inhibit muscle formation but promote adipogenesis. However, no research has addressed the question whether high intake of EPA and DHA affects brown fat development during gestation. The objective of this study was to measure the effect of EPA and DHA supplement on brown adipogenesis and potential pathways related to mitochondrial biosynthesis using fibroblasts as in vitro model. Using Oil-Red-O staining …

Dom Control Of Mercury Methylation In The Water Column Of A Meromictic Lake, Madalyn Bozinski

Renée Crown University Honors Thesis Projects - All

The trophic transfer and bioaccumulation of methyl mercury (MeHg) in aquatic ecosystems is a substantial concern, resulting in fish consumption advisories worldwide. Aquatic ecosystems have been identified as the critical environments that breed production of MeHg and low levels of initial accumulation in biota. MeHg production is a microbially-mediated process, occurring primarily at the transition between oxic and anoxic environments. This research aimed to assess the extent to which dissolved organic matter (DOM) affects methylation of mercury in the oligotrophic meromictic lake, Green Lake, in Fayetteville, NY and the warm monomictic lake, Seneca Lake, in Geneva, NY. General physical parameters …

Arabinose Substitution Effect On Xylan Rigidity And Self-Aggregation, Utsab Shrestha, Sydney Smith, Sai Venkatesh Pingali, Hui Yang, Mai Zahran, Llyod Breunig, Liza Wilson, Daniel Cosgrove, Hugh O'Neill, Loukas Petridis

Publications and Research

Substituted xylans play an important role in the structure and mechanics of the primary cell wall of plants. Arabinoxylans (AX) consist of a xylose backbone substituted with arabinose, while glucuronoarabinoxylans (GAX) also contain glucuronic acid substitutions and ferulic acid esters on some of the arabinoses. We provide a molecular-level description on the dependence of xylan conformational, selfaggregation properties and binding to cellulose on the degree of arabinose substitution. Molecular dynamics simulations reveal fully solubilized xylans with a low degree of arabinose substitution (lsAX) to be stiffer than their highly substituted (hsAX) counterparts. Small-angle neutron scattering experiments indicate that both wild-type …

Allosteric Mechanism Of The Circadian Protein Vivid Resolved Through Markov State Model And Machine Learning Analysis, Hongyu Zhou, Zheng Dong, Gennady M. Verkhivker, Brian D. Zoltowski, Peng Tao

Mathematics, Physics, and Computer Science Faculty Articles and Research

The fungal circadian clock photoreceptor Vivid (VVD) contains a photosensitive allosteric light, oxygen, voltage (LOV) domain that undergoes a large N-terminal conformational change. The mechanism by which a blue-light driven covalent bond formation leads to a global conformational change remains unclear, which hinders the further development of VVD as an optogenetic tool. We answered this question through a novel computational platform integrating Markov state models, machine learning methods, and newly developed community analysis algorithms. Applying this new integrative approach, we provided a quantitative evaluation of the contribution from the covalent bond to the protein global conformational change, and proposed an …

Targeted-Ion Mass Spectrometry For The Identification Of Forensically Relevant Biological Fluids And Samples From Sexual Assault Evidence, Heather Erin Mckiernan

Electronic Theses and Dissertations

Forensic practitioners have long sought efficient and reliable means for identifying those samples that are best suited for successful genetic profiling. Traditional serological screening methodologies rely upon enzyme activity and antibody-based serological tests. These tests can be consumptive, laborious and costly while reliance on antibody-based serological testing can be prone to error. Positive results resulting from non-target biological fluids, the potential for cross- reactivity and non-specific binding events yield merely presumptive results. This has led forensic biologists to omit serological testing, at least in the case of sexual assault kit samples, in favor of Y-Screen assays. While these Y-Screen approaches …

Reintegrating Biology Through The Nexus Of Information And Energy, Kim L. Hoke, Sara L. Zimmer, Mary Jo Ondrechen, Amedee Des Georges, Adam B. Roddy, Nicole R. Buan, Craig E. Williamson

Department of Biochemistry: Faculty Publications

Recent rapid advances in biology have led to diversification and sub-specialization of many fields, as well as a corresponding explosion of new findings. Advances in tools ranging from genomic techniques and high-resolution imaging to automated ecosystem- and biosphere-level sensors, along with correspondingly advanced analytics, have led to critical new insights that are transforming our understanding of biological systems. One of the consequences of these rapid advances has been accelerated splintering of biology into sub-disciplines with highly focused questions, vocabulary, and techniques. This splintering creates barriers to synergy across fields of biology and hinders the insights that could be gained at …

Visualizing The Invisible: A Guide To Designing, Printing, And Incorporating Dynamic 3d Molecular Models To Teach Structure–Function Relationships, Michelle Howell, Karin Van Dijk, Christine S. Booth, Tomáš Helikar, Brain A. Couch, Rebecca Roston

Department of Biochemistry: Faculty Publications

Understanding the intricate relationship between macromolecular structure and function represents a central goal of undergraduate biology education (1–3). In teaching complex three-dimensional (3D) concepts, instructors typically depend on static two-dimensional (2D) textbook images or computer-based visualization software, which can lead to unintended misconceptions (4–6). While chemical and molecular kits exist, these models cannot handle the size and detail of macromolecules. Consequently, students may graduate in the life sciences without understanding how structure underlies function or acquiring skills to translate between 2D and 3D molecular models (5, 7). Building on recent technological advances, 3D printing (3DP) potentiates an era in which …

Dna Uptake By Type Iv Filaments, Kurt H. Piepenbrink

Clark, Maria S. Dwiyanti, Kossonou G. Anzoua, Joe E. Brummer, Bimal Kumar Ghimire, Katarzyna Glowacka, Megan Hall, Kweon Heo, Xiaoli Jin, Alexander E. Lipka, Junhua Peng, Toshihiko Yamada, Ji Hye Yoo, Chang Yeon Yu, Hua Zhao, Stephen P. Long, Erik J. Sacks

Department of Biochemistry: Faculty Publications

To improve the efficiency of breeding of Miscanthus for biomass yield, there is a need to develop genomics‐assisted selection for this long‐lived perennial crop by relating genotype to phenotype and breeding value across a broad range of environments. We present the first genome‐wide association (GWA) and genomic prediction study of Miscanthus that utilizes multilocation phenotypic data. A panel of 568 Miscanthus sinensis accessions was genotyped with 46,177 single nucleotide polymorphisms (SNPs) and evaluated at one subtropical and five temperate locations over 3 years for biomass yield and 14 yield‐component traits. GWA and genomic prediction were performed separately for different years …

Brummer, Katarzyna Glowacka, Megan C. Hall, Kweon Heo, Xiaoli Jin, Junhua Peng, Toshihiko Yamada, Bimal Kumar Ghimire, Ji Hye Yoo, Chang Yeon Yu, Hua Zhao, Stephen P. Long, Erik J. Sacks

Department of Biochemistry: Faculty Publications

Overwintering ability is an important selection criterion for Miscanthus breeding in temperate regions. Insufficient overwintering ability of the currently leading Miscanthus biomass cultivar, M. ×giganteus (M×g) ‘1993–1780’, in regions where average annual minimum temperatures are −26.1°C (USDA hardiness zone 5) or lower poses a pressing need to develop new cultivars with superior cold tolerance. To facilitate breeding of Miscanthus, this study characterized phenotypic and genetic variation of overwintering ability in an M. sinensis germplasm panel consisting of 564 accessions, evaluated in field trials at three locations in North America and two in Asia. Genome‐wide association (GWA) and genomic …

Autophagy In Adipocyte Browning: Emerging Drug Target For Intervention In Obesity, Seung-Hyun Ro, Yura Jang, Jiyoung Bae, Isaac M. Kim, Cameron Schaecher, Zachery D. Shomo

Department of Biochemistry: Faculty Publications

Autophagy, lipophagy, and mitophagy are considered to be the major recycling processes for protein aggregates, excess fat, and damaged mitochondria in adipose tissues in response to nutrient status-associated stress, oxidative stress, and genotoxic stress in the human body. Obesity with increased body weight is often associated with white adipose tissue (WAT) hypertrophy and hyperplasia and/or beige/brown adipose tissue atrophy and aplasia, which significantly contribute to the imbalance in lipid metabolism, adipocytokine secretion, free fatty acid release, and mitochondria function. In recent studies, hyperactive autophagy in WAT was observed in obese and diabetic patients, and inhibition of adipose autophagy through targeted …

Chronic Alcohol Exposure Alters Circulating Insulin And Ghrelin Levels: Role Of Ghrelin In Hepatic Steatosis, Karuna Rasineni, Paul G. Thomes, Jacy L. Kubik, Edward N. Harris, Kusum K. Kharbanda, Carol A. Casey

Department of Biochemistry: Faculty Publications

Fatty liver is the earliest response of the liver to excessive ethanol consumption. Central in the development of alcoholic steatosis is increased mobilization of nonesterified free fatty acids (NEFAs) to the liver from the adipose tissue. In this study, we hypothesized that ethanol-induced increase in ghrelin by impairing insulin secretion, could be responsible for the altered lipid metabolism observed in adipose and liver tissue. Male Wistar rats were fed for 5–8 wk with control or ethanol Lieber-DeCarli diet, followed by biochemical analyses in serum and liver tissues. In addition, in vitro studies were conducted on pancreatic islets isolated from experimental …

An Arabidopsis Protoplast Isolation Method Reduces Cytosolic Acidification And Activation Of The Chloroplast Stress Sensor Sensitive To Freezing 2, Allison C. Barnes, Christian G. Elowsky, Rebecca Roston

Department of Biochemistry: Faculty Publications

Chloroplasts adapt to freezing and other abiotic stresses in part by modifying their membranes. One key-remodeling enzyme is SENSITIVE TO FREEZING2 (SFR2). SFR2 is unusual because it does not respond to initial cold stress or cold acclimation, instead it responds during freezing conditions in Arabidopsis. This response has been shown to be sensitive to cytosolic acidification. The unique lipid products of SFR2 have also been detected in response to non-freezing stresses, but what causes SFR2 to respond in these stresses is unknown. Here, we investigate protoplast isolation as a representative of wounding stress. We show that SFR2 oligogalactolipid products accumulate …

Nicotinamide adenine dinucleotide (NAD⁺) is an essential coenzyme required for all living organisms. In eukaryotic cells, the final step of NAD⁺ biosynthesis is exclusively cytosolic. Hence, NAD⁺ must be imported into organelles to support their metabolic functions. Three NAD⁺ transporters belonging to the mitochondrial carrier family (MCF) have been biochemically characterized in plants. AtNDT1 (At2g47490), focus of the current study, AtNDT2 (At1g25380), targeted to the inner mitochondrial membrane, and AtPXN (At2g39970), located in the peroxisomal membrane. Although AtNDT1 was presumed to reside in the chloroplast …

Charting A New Frontier Of Science By Integrating Mathematical Modeling To Understand And Predict Complex Biological Systems, Katharine White, Kira Mcentire, Nicole R. Buan, Kingshuk Ghosh, Lecia Robinson, Elisar Barbar

Department of Biochemistry: Faculty Publications

Biological systems are staggeringly complex. To untangle this complexity and make predictions about biological systems is a continuous goal of biological research. One approach to achieve these goals is to emphasize the use of quantitative measures of biological processes. Advances in quantitative biology data collection and analysis across scales (molecular, cellular, organismal, ecological) has transformed how we understand, categorize, and predict complex biological systems. Simultaneously, thanks to increased computational power, mathematicians, engineers and physical scientists -- collectively termed theoreticians -- have developed sophisticated models of biological systems at different scales. But there is still a disconnect between the two fields. …
