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

Karen 2020-08-01 · Penicillin binding protein 2a (PBP2a) is the key determinant of MRSA resistance. PBP2a allows cell wall biosynthesis in presence of most β-lactams. An outline of MSRA and PBP2a function, structure, and resistance mechanisms is presented. mecA encodes the protein PBP2A (penicillin-binding protein 2A), a transpeptidase that helps form the bacterial cell wall. PBP2A has a lower affinity for beta-lactam antibiotics such as methicillin and penicillin than DD-transpeptidase does, so it does not bind to the ringlike structure of penicillin-like antibiotics. Presence of the protein penicillin binding protein 2A (PBP2A) is responsible for the antibiotic resistance seen in methicillin-resistant Staphylococcus aureus (MRSA).

Penicillin binding protein 2a

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. Details Name Penicillin-binding protein 2a Kind protein Organism Streptococcus pneumoniae (strain ATCC BAA-255 / R6) Protein 1998-01-01 · Soluble penicillin-binding protein 2a: beta-lactam binding and inhibition by non-beta-lactams using a 96-well format.

Author information: (1)Department of Biochemistry, Merck Research Laboratories, Rahway, New Jersey 07065-0900, USA. jeff_toney@merck.com Bacterial proteins that share the property of binding irreversibly to PENICILLINS and other ANTIBACTERIAL AGENTS derived from LACTAMS. The penicillin-binding proteins are primarily enzymes involved in CELL WALL biosynthesis including MURAMOYLPENTAPEPTIDE CARBOXYPEPTIDASE ; PEPTIDE SYNTHASES ; TRANSPEPTIDASES ; and HEXOSYLTRANSFERASES .

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.

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. Methicillin‐resistant Staphylococcus aureus (MRSA) tolerates β‐lactam antibiotics by carrying out cell wall synthesis with the transpeptidase Penicillin‐binding protein 2a (PBP2a), which cannot be inhibited by β‐lactams.
