glycosyltransferase, MGT family. This model describes the MGT (macroside glycosyltransferase) subfamily of the UDP-glucuronosyltransferase family. Members include a number of glucosyl transferases for macrolide antibiotic inactivation, but also include transferases of glucose-related sugars for macrolide antibiotic production [Cellular processes, Toxin production and resistance].

Glycosyltransferase family 28 N-terminal domain. The glycosyltransferase family 28 includes monogalactosyldiacylglycerol synthase (EC 2.4.1.46) and UDP-N-acetylglucosamine transferase (EC 2.4.1.-). This N-terminal domain contains the acceptor binding site and likely membrane association site. This family also contains a large number of proteins that probably have quite distinct activities.

Glycosyl transferases, related to UDP-glucuronosyltransferase [Carbohydrate transport and metabolism / Signal transduction mechanisms]

This family includes the Gtfs, a group of homologous glycosyltransferases involved in the final stages of the biosynthesis of antibiotics vancomycin and related chloroeremomycin. Gtfs transfer sugar moieties from an activated NDP-sugar donor to the oxidatively cross-linked heptapeptide core of vancomycin group antibiotics. The core structure is important for the bioactivity of the antibiotics.
