Desosaminyl transferase EryCIII

Desosaminyl transferase EryCIII (, EryCIII) is an enzyme with systematic name dTDP-3-dimethylamino-4,6-dideoxy-alpha-D-glucopyranose:3-alpha-mycarosylerythronolide B 3-dimethylamino-4,6-dideoxy-alpha-D-glucosyltransferase. This enzyme catalyses the following chemical reaction


 * dTDP-3-dimethylamino-4,6-dideoxy-alpha-D-glucopyranose + 3-alpha-mycarosylerythronolide B $$\rightleftharpoons$$ dTDP + erythromycin D

The enzyme is involved in erythromycin biosynthesis.
