MRSA produces a penicillin binding protein 2a (mediated through the mecA gene), which is carried on the staphylococcal cassette chromosome mec (SCCmec) of which there are at least six different types recognized, and this results in resistance to all beta-lactam antibiotics. There is much debate on whether strains of MRSA are intrinsically more virulent than methicillin-susceptible isolates but it is agreed that MRSA causes the same range of infections resulting in excess healthcare costs

Methicillin‐resistant Staphylococcus aureus (MRSA) tolerates β‐lactam antibiotics by carrying out cell wall synthesis with the transpeptidase Penicillin‐binding protein 2a (PBP2a), which

The strains of S. aureus that have acquired the mecA gene for PBP2a are designated as methicillin-resistant S. aureus (MRSA). The performance of a rapid penicillin-binding protein 2a (PBP2a) detection assay, the Alere PBP2a culture colony test, was evaluated for identification of PBP2a-mediated beta-lactam resistance in human and animal clinical isolates of Staphylococcus intermedius group, Staphylococcus lugdunensis, and …. The mecA gene from methicillin-resistant Staphylococcus aureus 27r, which encodes the membrane-bound penicillin-binding protein 2a (PBP 2a), was cloned, sequenced, and expressed in Escherichia coli. PBP 2a is the major factor that mediates methicillin resistance in staphylococci. The penicillin-binding protein 2a (PBP2a) assay is a quick, accurate and inexpensive test for determining methicillin susceptibility in Staphylococcus aureus.

Presence of the protein penicillin binding protein 2A (PBP2A) is responsible for the antibiotic resistance seen in methicillin-resistant Staphylococcus aureus (MRSA). The β-lactam ring is a structure common to all β-lactam antibiotics. Other images Penicillin-binding protein 2a (PBP2a) is the primary β-lactam resistance determinant of methicillin-resistant Staphylococcus aureus (MRSA).

Unreviewed-Annotation score: -Protein inferred from homology i. Function i GO synthesis with the transpeptidase Penicillin-binding protein 2a (PBP2a), which cannot be inhibited by β-lactams. It has been proposed that PBP2a’s active site is protected by two loops to reduce the probability of it binding with β-lactams. Previous crystallographic studies suggested that this pro- The key determinant of the broad-spectrum beta-lactam resistance in MRSA strains is the penicillin-binding protein 2a (PBP2a). Because of its low affinity for beta-lactams, PBP2a provides transpeptidase activity to allow cell wall synthesis at beta-lactam concentrations that inhibit the beta-lactam-sensitive PBPs normally produced by S. aureus. Penicillin-binding proteins (PBPs) are bacterial cytoplasmic membrane proteins that catalyze the final steps of the peptidoglycan synthesis.
