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. Penicillins are thus bactericidal and are ineffective against resting organisms which are not making new cell wall. 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 Penicillin-binding protein 2a (PBP2a) is the primary β-lactam resistance determinant of methicillin-resistant Staphylococcus aureus (MRSA).

The penicillin-binding protein 2a (PBP2a) assay is a quick, accurate and inexpensive test for determining methicillin susceptibility in Staphylococcus aureus. A pre-post-study design was conducted using a PBP2a assay with and without the impact of an antimicrobial stewardship intervention to improve time to optimal therapy for methicillin-susceptible and methicillin-resistant S. aureus isolates.

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. High‐level resistance to β‐lactam antibiotics in methicillin‐resistant Staphylococcus aureus (MRSA) is due to expression of penicillin‐binding protein 2a (PBP2a), a transpeptidase that catalyzes cell‐wall crosslinking in the face of the challenge by β‐lactam antibiotics.

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 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. Resistance to β-lactams in Streptococcus pneumoniae is caused by low-affinity PBPs. S. pneumoniae PBP 2a belongs to the class A high-molecular-mass PBPs having both glycosyltransferase (GT) and transpeptide (TP) activities.
