Retaining glycosyltransferase mechanism studied by QM/MM methods: lipopolysaccharyl-α-1,4-galactosyltransferase C transfers α-galactose via an oxocarbenium ion-like transition state.

Abstract excerpt

Glycosyltransferases (GTs) catalyze the highly specific biosynthesis of glycosidic bonds and, as such, are important both as drug targets and for biotechnological purposes. Despite their broad interest, fundamental questions about their reaction mechanism remain to be answered, especially for those GTs that transfer the sugar with net retention of the configuration at the anomeric carbon (retaining...
