Electronic Theses and Dissertations

Plant secondary metabolites are essential for normal growth and development in plants ultimately affecting crop yield. They play roles ranging from appearance of the plants to defending against pathogen attack and herbivory. They have been used by humans for medicinal and recreational purposes amongst others. Glycosyltransferases catalyze the transfer of sugars from donor substrates to acceptors. Glucosyltransferases are a specific type of glycosyltransferases known to transfer glucose molecules from a glucose donor to a glucose acceptor (aglycone) producing the corresponding glucose secondary metabolite or glycone, in this case glucosides. It was hypothesized that SBIP68, a tobacco putative glucosyltransferase-like protein glucosylated …


Venom Peptide Induced Inhibition Of Escherichia Coli Atp Synthase, Sofiya Azim May 2015

Venom Peptide Induced Inhibition Of Escherichia Coli Atp Synthase, Sofiya Azim

Undergraduate Honors Theses

ATP is the main cellular energy generated by the enzyme ATP synthase in almost all organisms from bacteria to vertebrates. While malfunction of the ATP synthase complex is responsible for several disease conditions, the enzyme itself can be used as a potent molecular drug target to combat many diseases including microbial infections, cancer, tuberculosis, and obesity. Recent widespread escalation of antibiotic resistant microbes in general and E. coli in particular demands novel alternative approaches to combat microbial infections. Inhibition of ATP synthase by inhibitors such as peptides is known to deprive microbes of required energy, resulting in microbial cell death. …
