The PBP-2′ functions by substituting other penicillin binding proteins which have been Penicillin-binding protein 2 (PBP2) from N. gonorrhoeae is the major molecular target for β-lactam antibiotics used to treat gonococcal infections. PBP2 from penicillin-resistant strains of N. gonorrhoeae harbors an aspartate insertion after position 345 (Asp-345a) and 4-8 additional mutations, but how these alter the architecture of the protein is unknown.

They are a normal constituent of many bacteria; the name just reflects the way by which the protein was discovered. All β-lactam antibiotics bind to PBPs, which are essential for bacterial cell wall synthesis.

doi: 10.1146/annurev.bi.52.070183.004141. Mechanism of action of β-lactam antibacterials Beta-lactam antibacterials bind to several penicillin-binding proteins in bacteria. Some of these proteins are transpeptidases, which are required for cross-linking of the peptidoglycan layer of the cell wall surrounding certain bacteria and are essential for their survival. The penicillin-binding proteins, like the one shown on the left (PDB entry 3pte), use a serine amino acid in their reaction, colored purple here.

Penicillin's mechanism of action Penicillin and other antibiotics in the beta-lactam family contain a characteristic four-membered beta-lactam ring.

Penicillin kills bacteria through binding of the β-lactam antibiotics, as a group, are the most widely prescribed antibiotics. Penicillins bind to a number of receptor proteins, transpeptidases and carboxypeptidases called penicillin binding proteins (PBPs). Different microorganisms vary in the affinity of their PBPs for penicillin.

Some of these proteins are transpeptidases, which are required for cross-linking of the peptidoglycan layer of the cell wall surrounding certain bacteria and are essential for their survival. The penicillin-binding proteins, like the one shown on the left (PDB entry 3pte), use a serine amino acid in their reaction, colored purple here. The serine forms a covalent bond with a peptidoglycan chain, then releases it as it forms the crosslink with another part of the peptidoglycan network. 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).

Identification of Bacterial Target Proteins for the Salicylidene

Penicillin-binding proteins, found in bacterial membranes, covalently bind to penicillin [9, 10] and function as transpeptidases and carboxipeptidases [7, 9].
