Enzyme Information

2.1.1.164

Demethylrebeccamycin-D-glucose O-methyltransferase.

based on mapping to UniProt Q8KZ94

4'-demethylrebeccamycin + S-adenosyl-L-methionine = rebeccamycin + S-adenosyl-L-homocysteine.

-!- Catalyzes the last step in the biosynthesis of rebeccamycin, an indolocarbazole alkaloid produced by the bacterium Lechevalieria aerocolonigenes. -!- The enzyme is able to use a wide variety substrates, tolerating variation on the imide heterocycle, deoxygenation of the sugar moiety, and even indolocarbazole glycoside anomers.
