Protein target information for Penicillin-binding protein 2' (Penicillin binding protein 2a) (PBP2a) (Staphylococcus aureus). Find diseases associated with this biological target and compounds tested against it in bioassay experiments. 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 loss of Bacillus subtilis penicillin-binding protein (PBP) 2a, encoded by pbpA , was previously shown to slow spore outgrowth and result in an increased diameter of the outgrowing spore. Further analyses to define the defect in pbpA spore outgrowth have shown that (i) outgrowing pbpA spores exhibited only a slight defect in the rate of peptidoglycan (PG) synthesis compared to wild-type The bacterial peptidoglycan consists of glycan chains of repeating β-1,4-linked N -acetylglucosaminyl- N -acetylmuramyl units cross-linked through short peptide chains. The polymerization of the glycans, or glycosyltransfer (GT), and transpeptidation (TP) are catalyzed by bifunctional penicillin-binding proteins (PBPs). The β-lactam antibiotics inhibit the TP reaction, but their widespread Das PBP Penicillin binding protein 2A (PBP2A) ist an der Antibiotikum-Resistenz von MRSA beteiligt.

In Mitochondrien von Säugetieren existiert das Protein LACTB, ein Homolog des PBP-βL. Einzelnachweise The inhibition of penicillin-binding protein 2a (PBP2a) is a promising solution in overcoming resistance of methicillin resistance Staphylococcus aureus (MRSA).

Penicillin-binding protein 2a (PBP2a) of Staphylococcus aureus is refractory to inhibition by available beta-lactam antibiotics, resulting in resistance to these antibiotics.

Resistance is associated with production of a penicillin-binding protein (PBP), PBP 2a, with low affinity for binding beta-lactam antibiotics. Therefore, the effects of NaCl and nafcillin on amounts of PBP 2a produced and its binding affinity were examined and correlated with expression of resistance.

LifeSpan BioSciences currently sells 12 antibodies , 1 protein specific for Penicillin Binding Protein 2a. Penicillin binding protein 2a imparts to the human pathogen Staphylococcus aureus resistance to β-lactam antibiotics. Our structural characterization of the allosteric basis governing its resistance mechanism identifies a basis for the design of new antibacterials that can both activate and inhibit this key resistance enzyme. Detection of Penicillin Binding Protein 2a for the Identification of Methicillin Resistant S.aureus Using Top-down Proteomics PBP2a immunocapture was performed to facilitate method development with the native version of the S.aureus protein target and compare initial methods designed around the recombinant His 6-PBP2a protein.
