mecA encodes the protein PBP2A (penicillin-binding protein 2A), a transpeptidase that helps form the bacterial cell wall. PBP2A has a lower affinity for beta-lactam antibiotics such as methicillin and penicillin than DD-transpeptidase does, so it does not bind to the ringlike structure of penicillin-like antibiotics.

Penicillin pass through porins of gram negative bacterial cell wall. The penicillin then binds to penicillin binding protein linked the cell membrane to be a The consequences of the specific inhibition of penicillin binding proteins (Pbps) by beta-lactam antibiotics immediately before resumption of active growth in Escherichia coli suggest that inhibition of murein biosynthesis does not prevent the earlier steps of the initiation of cell growth in mass. Penicillin-binding proteins (PBPs) function in the late steps of murein biosynthesis (Probable). Probably required for both cortical and vegetative peptidoglycan synthesis (Probable). Although not usually required for cell division, in the absence of PBP 2B (pbpB) it becomes essential. Confers resistance to oxacillin and cephalexin (PMID: 28792086). Penicillin‐binding proteins were visualized after labelling with BOCILLIN FL, a fluorescent derivative of penicillin V (Molecular Probes).

Penicillin binding protein

Penicillin-binding proteins (PBPs) catalyze the polymerization of the glycan strand (transglycosylation) and the cross-linking between glycan chains (transpeptidation). Some PBPs can hydrolyze the last d -alanine of stem pentapeptides ( dd -carboxypeptidation) or hydrolyze the peptide bond connecting two glycan strands (endopeptidation).

Penicillin Binding Protein 1 Is Important in the Compensatory Response of Staphylococcus aureus to Daptomycin-Induced Membrane Damage and Is a Potential Target for β-Lactam-Daptomycin Synergy. Berti AD (1), Theisen E (2), Sauer JD (3), Nonejuie P (4), Olson J (4), Pogliano J (4), Sakoulas G (5), Nizet V (5), Proctor RA (6), Rose WE (7). β-Lactams are a class of antibiotics that target the synthesis of peptidoglycan, an essential component of the cell wall. β-Lactams inhibit the function of penicillin-binding proteins (PBPs), which form the cross-links between strands of peptidoglycan. Resistance to β-lactams complicates the treatment of bacterial infections.
