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 (PubMed:28792086). 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.

These PBPs are specifically involved in septal peptidoglycan synthesis. The K96243 genome encodes three PBP 3 proteins, with the additional homolog, BPSL3031, present on the large chromosome . Full story at http://pdb101.rcsb.org/learn/videos/staphylococcus-aureus-and-antibiotic-resistanceThe Methicillin-resistant Staphylococcus aureus (MRSA) is st The cell-cycle penicillin-binding protein 3 On the basis of published reports, the carboxy (PBP3) of Escherichia coli is a component of the end of the mature PBP3 appears to be important wall peptidoglycan assembly machinery involved both for penicillin binding and for ensuring the in cell septation. A pneumococcal strain, with a reduced amount of penicillin-binding protein 3 (PBP 3), permitted an analysis of the role of this protein in cefotaxime resistance. We observed that reduced amounts of PBP 3 sensitize the bacteria to high temperature, to brane-bound penicillin-binding protein 3 (P6P3) by the decapeptide MKGKEFQAWI was carried out by altering the amino-coding end of the ftsi gene. Inser-tion of the modified gene into a runaway-replication plasmid under the control of a fused Ipp promoter and lac promoter/operator, resulted in the overexpression The resulting thiol‐penicillin‐binding protein 3 was expressed under the control of the lacUV5 promoter in a high copy number plasmid. Constitutive expression of the thiol‐enzyme (but not of the wild‐type enzyme) was lethal, and the plasmid could only be maintained in E. coli strains that carried the lacIq mutation.

2. PRINCIPLES OF We have solved two crystal structures of penicillin-binding protein (PBP) 3 (PBP3) from MRSA, the apo form and a complex with the β-lactam antibiotic cefotaxime, and used electrospray mass spectrometry to measure its sensitivity to a variety of penicillin derivatives The soluble form of penicillin-binding protein 3 (sPBP3 ∗) from Streptococcus pneumoniae was expressed in Escherichia coli as a six-histidine fusion protein. The protein was purified and used to develop a microplate assay in direct competitive format for the detection of penicillins and cephalosporins in milk.

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.
