Di Berardino, M, Dijkstra, A, Stüber, D, Keck, W and Gubler, M (1996) The monofunctional glycosyltransferase of Escherichia coli is a member of a new class of peptidoglycan-synthesising enzymes. FEBS Lett. 392:184-8

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.
