PBP2x, beta-lactam receptor protein is derived from E Coli. It can be used in bioassays for the detection of beta-lactams antibiotics, including penicillin, amoxicillin, cefalotin, etc. It is highly sensitive and specific to beta-lactam groups.
Penicillin-binding proteins (PBPs) are a group of proteins that are characterized by their affinity for and binding of penicillin. They are a normal constituent of many bacteria; the name just reflects the way by which the protein was discovered. All β-lactam antibiotics (except for tabtoxinine-β-lactam, which inhibits glutamine synthetase) bind to PBPs, which are essential for bacterial cell wall synthesis. PBPs are members of a subgroup of enzymes called transpeptidases. Specifically, PBPs are DD-transpeptidases.
PBP2x belongs to PBPs and represents a primary resistance determinant for beta-lactams.
