Reaction: S-adenosyl-L-methionine + 3'-demethylstaurosporine = S-adenosyl-L-homocysteine + staurosporine
Other name(s): 3'-demethoxy-3'-hydroxystaurosporine O-methyltransferase; staurosporine synthase
Systematic name: S-adenosyl-L-methionine:3'-demethylstaurosporine O-methyltransferase
Comments: Catalyses the final step in the biosynthesis of staurosporine, an alkaloidal antibiotic that is a potent inhibitor of protein kinases, especially protein kinase C.
