Accepted name: 10-deoxymethynolide desosaminyltransferase
Reaction: dTDP-3-dimethylamino-3,4,6-trideoxy-α-D-glucopyranose + 10-deoxymethynolide = dTDP + 10-deoxymethymycin

Glossary: dTDP-3-dimethylamino-3,4,6-trideoxy-α-D-glucopyranose = dTDP-D-desosamine
Other name(s): glycosyltransferase DesVII; DesVII
Systematic name: dTDP-3-dimethylamino-3,4,6-trideoxy-α-D-glucopyranose:10-deoxymethynolide 3-dimethylamino-4,6-dideoxy-α-D-glucosyltransferase
Comments: DesVII is the glycosyltransferase responsible for the attachment of dTDP-D-desosamine to 10-deoxymethynolide or narbonolide during the biosynthesis of methymycin, neomethymycin, narbomycin, and pikromycin in the bacterium Streptomyces venezuelae. Activity requires an additional protein partner, DesVIII.
