Penicillin-binding proteins 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 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.

Penicillin resistance in Streptococcus spp. involves multiple mutations in both penicillin-binding proteins (PBPs) and non-PBP genes. Here, we studied the development of penicillin resistance in the oral commensal Streptococcus gordonii. Cyclic exposure of bacteria to twofold-increasing penicillin c …

1975 Aug 25;250(16):6578-85. The formation of functional penicillin-binding proteins. Hamilton TE, Lawrence PJ. A method was developed which permitted determination of the [14C]benzylpenicillin and [14C]Cephapirin binding capacity of rapidly growing Bacillus subtilis cells in liquid culture. Over the concentration range of the binding plateau (0.1 to 0.8 mug/ml), [14C By means of a defilamentation system which elicited the activity of penicillin-binding protein 3 in vivo, the structure of peptidoglycan made by this enzyme has been elucidated. This peptidoglycan, very probably of septal location, contained increased amounts of cross-linked peptidoglycan as well as a higher ratio of tripeptide-containing cross-linked subunits. The penicillin-binding proteins, like the one shown on the left (PDB entry 3pte ), use a serine amino acid in their reaction, colored purple here.

Action is dependent on the ability of penicillins to reach and bind penicillin-binding proteins (PBPs) located on the inner membrane of the bacterial cell wall. Penicillin -binding proteins (which include transpeptidases, carboxypeptidases, and endopeptidases) are enzymes that are involved in the terminal stages of assembling the bacterial cell wall and in reshaping the cell wall during growth and division.

Humphreys, in Medical Microbiology (Eighteenth Edition), 2012 Methicillin-resistant Staph. aureus (MRSA). MRSA produces a penicillin binding protein 2a (mediated through the mecA gene), which is carried on the staphylococcal cassette chromosome mec (SCCmec) of which there are at least six different types recognized, and this results in resistance to all beta-lactam antibiotics.

proteins that are unique to bacterial cells are therefore of special interest as drug targets. One class of proteins that has these distinct characteristics are the penicillin binding proteins (PBP’s): the target for the oldest used antibiotic, penicillin (Georgopapadakou et al., 1980, Macheboeuf et al., 2006).
