In enzymology, a 10" target="_blank">10-hydroxydihydrosanguinarine 10" target="_blank">10-O-methyltransferase (EC 2.1.1.119) is an enzyme that catalyzes the chemical reaction
S-adenosyl-L-methionine + 10" target="_blank">10-hydroxydihydrosanguinarine
⇌
{\displaystyle \rightleftharpoons }
S-adenosyl-L-homocysteine + dihydrochelirubine
Thus, the two substrates of this enzyme are S-adenosyl methionine and 10" target="_blank">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" target="_blank">10-hydroxydihydrosanguinarine 10" target="_blank">10-O-methyltransferase. This enzyme participates in alkaloid biosynthesis i.
