Identification Of Inhibitors Of The Glutaminyl And Prolyl Trna Synthetases From Pseudomonas Aeruginosa, Yaritza Escamilla

Theses and Dissertations

Antibiotic resistance is a growing global threat and bacterial infections caused by antibiotic resistant bacteria have become increasingly difficult and expensive to treat with most current antibiotics. Pseudomonas aeruginosa is a Gram-negative opportunistic pathogen and a leading cause of nosocomial infections and is the leading cause of mortality in cystic fibrosis patients. Aminoacyl-tRNA synthetases (aaRSs) are a class of enzymes that catalyze the covalent attachment of amino acids to their cognate tRNAs during protein biosynthesis. The glutaminyl- tRNA synthetase from P. aeruginosa was over-expressed, enzymatically characterized and developed into a screening platform for the discovery of chemical compounds that inhibit …
