HOW CHARGED RESIDUES INFLUENCE THE THERMAL STABILITY OF COLLAGEN: A STUDY WITH NATURAL AND NON-NATURAL AMINO ACIDS
(East Carolina University, 2020-09-16)
Triple-helical collagens are key structural proteins in mammals. Their ubiquity and diverse functions drive our interest into understanding their behavior at a fundamental level. This thesis describes a reductionist approach ...
SCREENING AND CHARACTERIZATION OF BIOCATALYSTS FOR SYNTHESIS OF WIELAND MIESCHER KETONE: A VERSATILE SYNTHETIC INTERMEDIATE
(East Carolina University, 2020-12-07)
Biocatalysts derived from biological molecules such as proteins, RNA, and DNA have long been exploited for applications in synthetic chemistry. Lipases, a versatile class of biocatalysts, are known to exhibit significant ...
DEVELOPMENT OF UNNATURAL SUBSTRATES AND TRYPTOPHAN AMINO ACIDS TO STUDY PROTON COUPLED ELECTRON TRANSFER IN ENZYMES
(East Carolina University, 2020-12-09)
Proton-coupled electron transfer plays an important role in substrate oxidation by C-H bond cleavage and long-range pathways associated with bioenergetics. This thesis is focused on the synthesis of unnatural substrates ...
Subcritical Water Extraction of Salvia miltiorrhiza

DIRECT ELECTROCHEMICAL ANALYSIS OF THE REDOX ACTIVITY OF TRYPTOPHAN AND TYROSINE IN MODIFIED AZURINS: THE IMPACT OF THE PROTEIN ENVIRONMENT
(East Carolina University, 2021-05-03)
Proton-coupled electron transfer (PCET) is a biological process essential to life. It is imperative for respiration in animals as well as photosynthesis in plants. Long-range PCET is often facilitated by redox-active amino ...
Transthyretin Amyloidosis: Proteolytic cleavage accelerates G53A TTR misfolding and aggregation
(East Carolina University, 2020-06-22)
The proteolytic cleavage of the peptide bond Lys48-Thr49 of the CD loop in TTR pathological mutants S52P and E51_S52dup was previously demonstrated to promote aggregation as a result of tetrameric structure destabilization. ...
