WebDec 27, 2016 · Penicillin-binding proteins (PBPs) function as transpeptidases, carboxypeptidases, or endopeptidases during peptidoglycan synthesis in bacteria. As the well-known drug targets for β-lactam antibiotics, the physiological functions of PBPs and whether they are essential for growth are of significant interest. The pathogen … WebThe essential function of penicillin-binding protein 2 (PBP2) in methicillin-susceptible Staphylococcus aureus RN4220 was clearly established by placing the pbp2 gene under control of the inducible P(spac) promoter; the resulting bacteria were unable to grow in the absence of inducer. In contrast, the deficit in PBP2 caused by inhibition of ...
