Glycopeptide antibiotics of the vancomycin group are of crucial clinical importance in the treatment of methicillin resistant Staphylococcus aureus (MRSA)--the often lethal 'super-bug'--characterized by its resistance to a wide range of antibiotics in common use. The antibiotics exert their physiological

The cooperativity between binding of cell wall precursor analogs (ligands) to and antibiotic dimerization of the clinically important vancomycin group antibiotics was investigated by nuclear magnetic resonance. When dimerization was weak in the absence of a ligand, the increase in

Titration of the active-site serine DD-peptidase of Streptomyces R61 shows that formation of acyl enzyme during hydrolysis of the substrate Ac2-L-Lys-D-Ala-D-Ala and enzyme inactivation by the beta-lactam compounds benzylpenicillin, N-acetylampicillin and ampicillin relies on the acidic form of an enzyme's
