IntEnz Enzyme Nomenclature


Accepted name:
4'-demethylrebeccamycin synthase
Other names:
arcyriaflavin A N-glycosyltransferase
Systematic name:
4'-demethylrebeccamycin D-glucose-lyase



This enzyme catalyses a step in the biosynthesis of rebeccamycin, an indolocarbazole alkaloid produced by the bacterium Lechevalieria aerocolonigenes. The enzyme is a glycosylase, and acts in the reverse direction to that shown. It has a wide substrate range, and was shown to glycosylate several substrates, including the staurosporine aglycone, EJG-III-108A, J-104303, 6-N-methyl-arcyriaflavin C and indolo-[2,3-a]-carbazole [1,2].
