4'-demethylrebeccamycin synthase

4′-Demethylrebeccamycin synthase (EC 4.3.3.5, arcyriaflavin A N-glycosyltransferase, RebG) is an enzyme with systematic name 4′-demethylrebeccamycin D -glucose-lyase. It catalyses the following chemical reaction


 * 4′-O-demethylrebeccamycin + H2O $$\rightleftharpoons$$ dichloro-arcyriaflavin A + β- D -glucose

This enzyme catalyses a step in the biosynthesis of rebeccamycin.
