Glossary: dTDP-α-D-desosamine = dTDP-3-(dimethylamino)-3,4,6-trideoxy-α-D-glucose

Other name(s): desV (gene name); megDII (gene name); eryCI (gene name)

Systematic name: dTDP-3-amino-3,4,6-trideoxy-α-D-glucose:2-oxoglutarate aminotransferase

Comments: A pyridoxal-phosphate protein. The enzyme is involved in the biosynthesis of dTDP-α-D-desosamine, a sugar found in several bacterial macrolide antibiotics including erythromycin, megalomicin A, mycinamicin II, and oleandomycin. The reaction occurs in the reverse direction.
