    • The interaction of representative beta-lactam antibiotics with a bacterial enzyme target has been mapped in three dimensions using X-ray diffraction data to 2.25 A resolution. Examination of complexes of cephalosporin C, benzylmonobactam, and alpha-(2,3)-methylenepenicillin G with the D-alanyl-D-alanine transpeptidase-carboxypeptidase from Streptomyces R61 shows that the enzyme's reactive serine has acylated the beta-lactam ring of each inhibitor. The known half-lives of the three acyl… CONTINUE READING
