DTDP 3 amino 3,4,6 trideoxy alpha D glucopyranose N,N dimethyltransferase

DTDP-3-amino-3,4,6-trideoxy-alpha-D-glucopyranose N,N-dimethyltransferase (EC 2.1.1.234, DesVI) is an enzyme with systematic name S-adenosyl-L-methionine:dTDP-3-amino-3,4,6-trideoxy-alpha-D-glucopyranose 3-N,N-dimethyltransferase. This enzyme catalyses the following chemical reaction

2 S-adenosyl-L-methionine + dTDP-3-amino-3,4,6-trideoxy-alpha-D-glucopyranose ⇌ 2 S-adenosyl-L-homocysteine + dTDP-3-dimethylamino-3,4,6-trideoxy-alpha-D-glucopyranose

The enzyme is involved in the biosynthesis of desosamine.
