Flavonol Glucosylation: A Structural Investigation Of The Flavonol Specific 3-O Glucosyltransferase Cp3gt, Aaron S. Birchfield
Flavonol Glucosylation: A Structural Investigation Of The Flavonol Specific 3-O Glucosyltransferase Cp3gt, Aaron S. Birchfield
Electronic Theses and Dissertations
Flavonoid glycosyltransferases (GTs), enzymes integral to plant ecological responses and human pharmacology, necessitate rigorous structural elucidation to decipher their mechanistic function and substrate specificity, particularly given their role in the biotransformation of diverse pharmacological agents and natural products. This investigation delved into a comprehensive exploration of the flavonol 3-O GT from Citrus paradisi (Cp3GT), scrutinizing the impact of a c-terminal c-myc/6x histidine tag on its enzymatic activity and substrate specificity, and successfully achieving its purification to apparent homogeneity. This established a strong foundation for potential future crystallographic and other structure/function analyses. Through the strategic implementation of site-directed mutagenesis, a thrombin …
A Cancer-Specific Study On The Differentially Expressed Protein-Protein Interactions Of Fumarate Hydratase, Sydney Lac
A Cancer-Specific Study On The Differentially Expressed Protein-Protein Interactions Of Fumarate Hydratase, Sydney Lac
Dissertations & Theses (Open Access)
Fumarate hydratase (FH) is an enzyme used in the Krebs Cycle to convert fumarate to malate, and it is controlled by the FH gene. In this paper, we will investigate its role in Uterine Corpus Endometrial Carcinoma (UCEC) and how FH-deficient cells affect tumorigenesis. It is well-established that FH has been extensively studied in connection with renal cell carcinoma, skin and uterine leiomyomas, pheochromocytoma, and paraganglioma. However, we aim to construct an interaction network of significant genes related to the FH gene under conditions of FH deficiency in the Kreb Cycle. Creating an interactive network that illustrates the interconnectedness of …
State-Of-The-Art Approaches For Sequencing, Assembling And Annotating Naphthenic Acid Degrading Bacterial Metagenomes, Henry H. Say
State-Of-The-Art Approaches For Sequencing, Assembling And Annotating Naphthenic Acid Degrading Bacterial Metagenomes, Henry H. Say
Electronic Thesis and Dissertation Repository
Naphthenic acids (NAs) are the main toxic component of oil refinery wastewater and require special processes to be removed. Harnessing bacterial biodegradation for NA removal has the potential to be effective, yet NA-degrading bacteria and pathways are poorly understood and uncharacterized. To improve our understanding of NA degradation, I characterize the metagenomes of novel NA-degrading bacterial communities seeded in NA-enriched granulated activated carbon (GAC) filters. I demonstrate methods that maximize the throughput of extraction, sequencing, and annotation of novel metagenomes - producing 72 MAGs and other 5432 circular contigs - 226 of which were putative phages. I also include state-of-the-art …
