Function

DAC_STRSR Catalyzes distinct carboxypeptidation and transpeptidation reactions during the last stages of wall peptidoglycan synthesis. Mistaking a beta-lactam antibiotic molecule for a normal substrate (i.e. a D-alanyl-D-alanine-terminated peptide), it becomes immobilized in the form of a long-lived, serine-ester-linked acyl enzyme and thus behave as penicillin-binding protein (PBP).

Publication Abstract from PubMed

The cell wall imparts structural strength and shape to bacteria. It is made up of polymeric glycan chains with peptide branches that are cross-linked to form the cell wall. The cross-linking reaction, catalyzed by transpeptidases, is the last step in cell wall biosynthesis. These enzymes are members of the family of penicillin-binding proteins, the targets of beta-lactam antibiotics. We report herein the structure of a penicillin-binding protein complexed with a cephalosporin designed to probe the mechanism of the cross-linking reaction catalyzed by transpeptidases. The 1.2-A resolution x-ray structure of this cephalosporin bound to the active site of the bifunctional serine type D-alanyl-D-alanine carboxypeptidase/transpeptidase (EC ) from Streptomyces sp. strain R61 reveals how the two peptide strands from the polymeric substrates are sequestered in the active site of a transpeptidase. The structure of this complex provides a snapshot of the enzyme and the bound cell wall components poised for the final and critical cross-linking step of cell wall biosynthesis.
