Definition: Bacterial proteins that share the property of binding irreversibly to PENICILLINS and other ANTIBACTERIAL AGENTS derived from LACTAMS. The penicillin-binding proteins are primarily enzymes involved in CELL WALL biosynthesis including MURAMOYLPENTAPEPTIDE CARBOXYPEPTIDASE; PEPTIDE SYNTHASES; TRANSPEPTIDASES; and HEXOSYLTRANSFERASES.
Other names Penicillin-Binding Protein 3; Penicillin-Binding Protein 2b; Penicillin-Binding Protein 2a; Penicillin-Binding Protein 2; Penicillin-Binding Protein 1b; Penicillin-Binding Protein 1A; Penicillin-Binding Protein 1; Penicillin-Binding Protein; Synthetase, Peptidoglycan; Proteins, Penicillin-Binding; Protein 1b, Penicillin-Binding; Protein 1A, Penicillin-Binding; Penicillin Binding Proteins; Penicillin Binding Protein 7; Penicillin Binding Protein 6; Penicillin Binding Protein 5; Penicillin Binding Protein 4; Penicillin Binding Protein 3; Penicillin Binding Protein 2b; Penicillin Binding Protein 2a
