Thus, the two substrates of this enzyme are S-adenosyl methionine and 3'-demethylstaurosporine, whereas its two products are S-adenosylhomocysteine and staurosporine.
This enzyme belongs to the family of transferases, specifically those transferring one-carbon group methyltransferases. The systematic name of this enzyme class is S-adenosyl-L-methionine:3'-demethylstaurosporine O-methyltransferase. Other names in common use include 3'-demethoxy-3'-hydroxystaurosporine O-methyltransferase, and staurosporine synthase.
