10-hydroxydihydrosanguinarine 10-O-methyltransferase

In enzymology, a 10-hydroxydihydrosanguinarine 10-O-methyltransferase (EC 2.1.1.119) is an enzyme that catalyzes the chemical reaction

S-adenosyl-L-methionine + 10-hydroxydihydrosanguinarine ${\displaystyle \rightleftharpoons }$ S-adenosyl-L-homocysteine + dihydrochelirubine

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

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 .
