10-hydroxydihydrosanguinarine 10-O-methyltransferase

Jump to: navigation, search

In enzymology, a 10-hydroxydihydrosanguinarine 10-O-methyltransferase (EC is an enzyme that catalyzes the chemical reaction

S-adenosyl-L-methionine + 10-hydroxydihydrosanguinarine S-adenosyl-L-homocysteine + dihydrochelirubine

Thus, the two substrates of this enzyme are S-adenosyl methionine and 10-hydroxydihydrosanguinarine, whereas its two products are S-adenosylhomocysteine and dihydrochelirubine.

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:10-hydroxydihydrosanguinarine 10-O-methyltransferase. This enzyme participates in alkaloid biosynthesis i.
