The performance of a rapid penicillin-binding protein 2a (PBP2a) detection assay, the Alere PBP2a culture colony test, was evaluated for identification of PBP2a-mediated beta-lactam resistance in human and animal clinical isolates of Staphylococcus intermedius group, Staphylococcus lugdunensis, and ….

Methicillin-resistant Staphylococcus aureus (MRSA) is one of the "superbug" family, manifesting resistance through the production of a penicillin binding protein, PBP2a, an enzyme that provides its transpeptidase activity to allow cell wall biosynthesis. Penicillin binding protein 2a: An overview and a medicinal chemistry perspective 1. Introduction. Antimicrobial resistance is currently considered one of the major health threats worldwide with an 2. Bacterial cell-wall biosynthesis and the role of penicillin-binding proteins.

Methicillin‐resistant Staphylococcus aureus (MRSA) tolerates β‐lactam antibiotics by carrying out cell wall synthesis with the transpeptidase Penicillin‐binding protein 2a (PBP2a), which

The relative efficacy of each antibiotic was compared to vancomycin in a rabbit model of aortic valve endocarditis caused by either a methicillin-susceptible or methicillin-resistant Penicillin-binding protein 2a from methicillin-resistant Staphylococcus aureus: kinetic characterization of its interactions with beta-lactams using electrospray mass spectrometry. W P Lu, Y Sun, M D Bauer, S Paule, P M Koenigs, W G Kraft Biochemistry 1999 May 18, 38 (20): 6537-46 2020-05-01 Penicillins act by inhibiting the enzymes (penicillin binding proteins, PBPs) involved in the cross-linking of the peptidoglycan layer of the cell wall, which is weakened, and this leads to osmotic rupture.

lococcus aureus contain an extra penicillin binding protein (PBP) 2A in addition to four PBPs present in all staphylococcal strains. This extra PBP is thought to be a transpeptidase essential for the continued cell wall synthesis and growth in the presence of &lactam antibiotics. As an approach of testing this hypothesis

The strains of S. aureus that have acquired the mecA gene for PBP2a are designated as methicillin-resistant S. aureus (MRSA).

This review discusses the Penicillins act by inhibiting the enzymes (penicillin binding proteins, PBPs) involved in the cross-linking of the peptidoglycan layer of the cell wall, which is weakened, and this leads to osmotic rupture. Penicillins are thus bactericidal and are ineffective against resting organisms which are not making new cell wall.
