ACTIVE SITE RESTRUCTURING REGULATES LIGAND RECOGNITION IN CLASSA PENICILLIN-BINDING PROTEINS (PBPS)
Overview
Bacterial cell division is a complex, multimolecular process that requires, biosynthesis of new peptidoglycan by penicillin-binding proteins (PBPs), during cell wall elongation and septum formation steps. Streptococcus, pneumoniae has three bifunctional (class A) PBPs that catalyze both, polymerization of glycan chains (glycosyltransfer) and cross-linking of, pentapeptidic bridges (transpeptidation) during the peptidoglycan, biosynthetic process. In addition to playing important roles in cell, division, PBPs are also the targets for beta-lactam antibiotics and thus, play key roles in drug-resistance mechanisms. The crystal structure of a, soluble form of pneumococcal PBP1b (PBP1b*) has been solved to 1.9 A, thus, providing previously undescribed structural information regarding a class, A ...
