Confers resistance to oxacillin and cephalexin (PMID: 28792086). 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.

Recently, it was shown that RodA-a member of the unrelated SEDS … (A) Scheme of the reactions of a class A penicillin-binding protein (PBP) (GTase-TPase) with unlabelled lipid II and the two versions of labelled lipid II, yielding a peptidoglycan (PG) product that shows FRET.

Penicillin‐binding proteins were visualized after labelling with BOCILLIN FL, a fluorescent derivative of penicillin V (Molecular Probes). BOCILLIN FL was dissolved in methanol to a stock concentration of 250 µM as per the manufacturer's directions.

Cell wall formation.

Some assemble long chains of sugars with little peptides sticking out in all directions. 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). Endopeptidation and transpeptidation are reverse activities.

Penicillin-binding protein (PBP) 3, or ftsI, is an essential transpeptidase in Mycobacterium tuberculosis (Mtb) required for cell division, and thus it is an important drug target. Structures of apo Mtb PBP3 and of complexes with five β -lactams, including meropenem and faropenem, reveal how they cause inactivation via formation of hydrolytically stable acyl-enzyme complexes.
