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 ...

WebThe past 20 years have seen not only a dramatic increase in the number of β-lactam antibiotics synthesized or discovered but also major developments in our understanding of how these antibacterial agents act as inhibitors of peptidoglycan biosynthesis. By 1974 it was established that bacterial membranes contain multiple penicillin-sensitive enzymes … WebFeb 24, 2024 · Penicillin-binding proteins are generally enzymes involved in peptidoglycan biosynthesis, so contribute essential roles in bacterial cell wall biosynthesis. WebNov 26, 2024 · Key proteins transferred by epididymal extracellular vesicles (EVs) to the transiting sperm cells contribute to their centrosomal maturation and developmental potential.
