Function

[MRDA_ECOLI] Catalyzes cross-linking of the peptidoglycan cell wall (PubMed:3009484). Responsible for the determination of the rod shape of the cell (PubMed:1103132). Is probably required for lateral peptidoglycan synthesis and maintenance of the correct diameter during lateral and centripetal growth (PubMed:12519203).^[1] ^[2] ^[3]

Publication Abstract from PubMed

Penicillin-binding proteins (PBPs) are the targets of the beta-lactams, the most successful class of antibiotics ever developed against bacterial infections. Unfortunately, the worldwide and rapid spread of large spectrum beta-lactam resistance genes such as carbapenemases is detrimental to the use of antibiotics in this class. New potent PBP inhibitors are needed, especially compounds that resist beta-lactamase hydrolysis. Here we describe the structure of the E. coli PBP2 in its Apo form and upon its reaction with 2 diazabicyclo derivatives, avibactam and CPD4, a new potent PBP2 inhibitor. Examination of these structures shows that unlike avibactam, CPD4 can perform a hydrophobic stacking on Trp370 in the active site of E. coli PBP2. This result, together with sequence analysis, homology modeling, and SAR, allows us to propose CPD4 as potential starting scaffold to develop molecules active against a broad range of bacterial species at the top of the WHO priority list.
