Abstract
The study of the interactions between the Tyr280Phe mutant of the Streptomyces R61 DD-peptidase, various substrates and beta-lactam antibiotics shows that Tyr280 is involved not only in the formation of the acylenzyme with the peptide substrate and beta-lactam antibiotics, but also and specifically in the catalysis of the transpeptidation reaction. Surprisingly, this residue does not belong to the conserved structural and functional elements which characterise the penicillin-recognising enzymes.
