Function i GO - Molecular function i. penicillin binding Source: InterPro; Complete GO annotation on Details Name Penicillin-binding protein 2a Kind protein Organism Streptococcus pneumoniae (strain ATCC BAA-255 / R6) Protein Penicillin-binding protein 2a (PBP2a) of Staphylococcus aureus is refractory to inhibition by available beta-lactam antibiotics, resulting in resistance to these antibiotics. The strains of S. aureus that have acquired the mecA gene for PBP2a are designated as methicillin-resistant S. 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. The water-soluble form of PBP 2a protein from S. aureus 27r retained the same binding efficiency for beta-lactam antibiotics as the unmodified membrane-bound PBP 2a from S. aureus 27r.

It has been proposed that PBP2a’s active site is protected by two loops to reduce the probability of it binding with β-lactams.

It is Penicillin Binding Protein 2a. Penicillin Binding Protein 2a listed as PBP2a. 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.

Einzelnachweise The inhibition of penicillin-binding protein 2a (PBP2a) is a promising solution in overcoming resistance of methicillin resistance Staphylococcus aureus (MRSA). A potential approach in achieving this is by combining natural product with currently available antibiotics to restore the activity as well as to amplify the therapeutic ability of the drugs. There are at least two mechanisms that Staphylococci can evade beta-lactam toxicity which are by synthesizing the penicillin-binding protein 2a (PBP2a) and β-lactamases . In normal circumstances, Staphylococcus aureus strains produce penicillin-binding proteins (PBPs) for synthesis of bacterial cell wall. The key determinant of the broad-spectrum beta-lactam resistance in MRSA strains is the penicillin-binding protein 2a (PBP2a) There are at least two mechanisms that Staphylococci can evade beta-lactam toxicity which are by synthesizing the penicillin-binding protein 2a (PBP2a) and 18 Jan 2017 An enzyme, called penicillin-binding protein 2a (PBP2a), is brought into this biosynthetic pathway to complete the cross-linking.
