PBP2-like beta-lactam resistant peptidoglycan transpeptidase [AMR Gene Family]

Ontology CARD's Antibiotic Resistance Ontology
Accession ARO:3009312
DefinitionPeptidoglycan transpeptidase proteins involved in bacterial cell wall formation and which have decreased susceptibility to some beta-lactam antibiotics. These alternative transpeptidases are found in certain organisms, like Staphylococcus aureus, and have lower affinity for penicillin-like antibiotics, such as methicillin. In these organisms, these proteins do not bind to the beta-lactam ring and therefore transpeptidase activity continues in the presence of beta-lactams, thereby conferring resistance to these drugs. These proteins are commonly clinically associated with methicillin-resistant Staphylococcus aureus (MRSA).
