On the other hand, molecular docking showed a possible interaction between terpinen-4-ol and penicillin-binding protein 2a (PBP2a), which is one of the main molecules involved in S. aureus mecA1 - Penicillin binding protein 2a - Staphylococcus pseudintermedius - mecA1 gene & protein UniProtKB - B5M0C8 (B5M0C8_STAPS) of penicillin-binding protein 2a (PBP2a), a transpeptidase that catalyzes cell-wall crosslinking in the face of the challenge by b-lactam antibiotics. The activity of this protein is regulated by allostery at a site 60 Å distant from the active site, where crosslinking of cell wall takes place. This review discusses the Binding affinity for penicillin-binding protein 2a correlates with in vivoactivity of beta-lactam antibiotics against methicillin-resistant Staphylococcus aureus. Chambers HF(1), Sachdeva M, Kennedy S. Author information: (1)Department of Medicine, University of California, San Francisco. The beta-lactam antibiotics ticarcillin, nafcillin, imipenem, and ampicillin,which differ in antibacterial activity against methicillin-resistant strains ofStaphylococcus aureus, were examined for affinity Penicillin-binding proteins (PBPs) are bacterial cytoplasmic membrane proteins that catalyze the final steps of the peptidoglycan synthesis.

It has been proposed that PBP2a’s active site is protected by two loops to reduce the probability of it binding with β-lactams. Previous crystallographic studies suggested that this pro- The key determinant of the broad-spectrum beta-lactam resistance in MRSA strains is the penicillin-binding protein 2a (PBP2a). Because of its low affinity for beta-lactams, PBP2a provides transpeptidase activity to allow cell wall synthesis at beta-lactam concentrations that inhibit the beta-lactam-sensitive PBPs normally produced by S. aureus.

The gene product, PBP 2a (also termed PBP 2′), is an inducible 76-kDa penicillin-binding protein (PBP). PBP 2a has low affinity for binding β-lactam antibiotics and apparently can substitute for the essential functions of high-affinity PBPs at otherwise lethal concentrations of antibiotic.

INTENDED USE This test is a rapid latex agglutination assay, detecting PBP2/ (also called PBP2a)7, in isolates of Staphylococcus, as an aid in identifying methicillin-resistant Staphylococcus aureus (MRSA) and methicillin-resistant coagulase-negative staphylococci. 2. PRINCIPLES OF Staphylococcus aureus, were examined for affinity to penicillin-binding protein (PBP) 2a, which mediates methicillin resistance. 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 (PBP2a) is the primary β-lactam resistance determinant of methicillin-resistant Staphylococcus aureus (MRSA). MecA, the gene coding for PBP2a, was cloned with the membrane-anchoring region at the N-terminus deleted. The truncated protein (PBP2a*) was overexpressed in Escherichia coli mostly in the soluble form accounting for ∼25% of soluble cell protein and was PBP2a - Penicillin Binding Protein 2a.
