Abstract

Using conserved fingerprints in the glycosyltransferase (GTase) domain of high-molecular-weight penicillin-binding proteins (PBP), a gene (mgt) encoding a putative monofunctional glycosyltransferase has been identified in Haemophilus influenzae and in other bacteria] species. Here we report the cloning of the homologous Escherichia coli gene and show that the solubilised membrane fraction of E. coli cells overexpressing the mgt gene contain a significantly increased peptidoglycan synthesis activity. In contrast to the high-molecular-weight PBPs, this activity is not inhibited by Flavomycin.
