ID 2.1.1.234 DE dTDP-3-amino-3,4,6-trideoxy-alpha-D-glucopyranose DE N,N-dimethyltransferase. CA dTDP-3-amino-3,4,6-trideoxy-alpha-D-glucose + 2 S-adenosyl-L-methionine = CA dTDP-alpha-D-desosamine + 2 H(+) + 2 S-adenosyl-L-homocysteine. CC -!- The enzyme is involved in the biosynthesis of desosamine, CC a 3-(dimethylamino)-3,4,6-trideoxyhexose found in certain macrolide CC antibiotics such as erthyromycin, azithromycin, and clarithromycin.
