CRYSTAL STRUCTURE OF THE STREPTOMYCES K15 DD-TRANSPEPTIDASE
|
OverviewOverview
The serine DD-transpeptidase/penicillin-binding protein of Streptomyces, K15 catalyzes peptide bond formation in a way that mimics the, penicillin-sensitive peptide cross-linking reaction involved in bacterial, cell wall peptidoglycan assembly. The Streptomyces K15 enzyme is peculiar, in that it can be considered as an intermediate between classical, penicillin-binding proteins, for which benzylpenicillin is a very, efficient inactivator, and the resistant penicillin-binding proteins that, have a low penicillin affinity. With its moderate penicillin sensitivity, the Streptomyces K15 DD-transpeptidase would be helpful in the, understanding of the structure-activity relationship of this, penicillin-recognizing protein superfamily. The structure of the, Streptomyces K15 enzyme has been ... [(full description)]
