ARO:3000617mecAmecA encodes an alternative PBP2a protein involved in bacterial cell wall formation. These proteins are acquired by lateral gene transfer and commonly associated with methicillin-resistant Staphylococcus aureus (MRSA). These proteins have lower affinity for penicillin-like antibiotics and therefore are able to perform peptidoglycan synthesis in the presence of beta-lactams.CARD (4.0.2)
