    beta-Lactam compounds are the most widely used antibiotics. They inactivate bacterial DD-transpeptidases, also called penicillin-binding proteins (PBPs), involved in cell-wall biosynthesis. The most common bacterial resistance mechanism against beta-lactam compounds is the synthesis of beta-lactamases that hydrolyse beta-lactam rings. These enzymes are believed to have evolved from cell-wall DD-peptidases. Understanding the biochemical and mechanistic features of the beta-lactam targets is crucial because of the increasing number of resistant bacteria. DAP is a D-aminopeptidase produced by Ochrobactrum anthropi. It is inhibited by various beta-lactam compounds and shares approximately 25% sequence identity with the R61 DD-carboxypeptidase and the class C beta-lactamases.
