Method Development For Enhancing Sensitivity Of Dynamic Nuclear Polarization Nuclear Magnetic Resonance Spectroscopy For Structural Studies Of Pkc-Drug Interactions, Patrick Terrence Judge
Method Development For Enhancing Sensitivity Of Dynamic Nuclear Polarization Nuclear Magnetic Resonance Spectroscopy For Structural Studies Of Pkc-Drug Interactions, Patrick Terrence Judge
Arts & Sciences Electronic Theses and Dissertations
To perform the most relevant structural studies on biological systems, experiments need to be carried out when the target proteins are in their endogenous cellular environment. Nuclear magnetic resonance (NMR) is well-suited to probe the structure and dynamics of a wide variety of systems, including biologically relevant proteins. However, NMR suffers from an inherent lack of sensitivity. Dynamic nuclear polarization (DNP) NMR is a powerful technique that is used to enhance NMR sensitivity by transferring the greater polarization of exogenously doped electron spins to nuclear spins of interest though the use of a high-power microwave source. Solid effect radicals offer …

MicroRNA (miRNA), as a distinct class of biological regulators and a ”guide” member of non-coding RNA-protein complexes (RNPs), regulates more than 60% of protein-coding genes expression through base-pairing with targeted messenger RNA (mRNA) in the RNA-Induced Silencing Complex (RISC). Most of miRNAs identified in human, are conserved in other animals, which have preferentially conserved interaction sites particularly in 3’ untranslated regions (3’UTRs) of many human messenger mRNAs.The capability of a single miRNA to target more than hundreds of mRNAs, suggests that miRNAs influence essentially all developmental process and diseases, which also makes them interesting candidates as therapeutics agents. The primary …
Molecular Dynamics Simulations Provide Insight Into Stability Of Hyperthermophilic Endoglucanases, Logan E. Sheffield
Molecular Dynamics Simulations Provide Insight Into Stability Of Hyperthermophilic Endoglucanases, Logan E. Sheffield
Electronic Theses and Dissertations
Endoglucanases play a key role in the industrial production of bioethanol, but the most efficient method requires the utilization of high temperatures and is currently limited by the thermostability of endoglucanases. For this reason, it would be beneficial to discover more high-efficiency, thermostable enzymes to utilize in the hydrolytic process. In this study molecular dynamics simulations were performed on structurally similar endoglucanases with varying levels of thermostability to gain insight on what factors contribute to thermostability in endoglucanases. RMSD, RMSF, PCA, hydrogen bonding and salt bridges were analyzed. Finally, protein energy networks were constructed from nonbonded interaction potentials and analysis …
