In enzymology a tetrahydrocolumbamine 2-O-methyltransferase (EC 2.1.1.89) is an enzyme that catalyzes the chemical reactionS-adenosyl-L-methionine + 581313a-tetrahydrocolumbamine S-adenosyl-L-homocysteine + tetrahydropalmatineThus the two substrates of this enzyme are S-adenosyl methionine and 581313a-tetrahydrocolumbamine whereas its two products are S-adenosylhomocysteine and tetrahydropalmatine.This enzyme belongs to the family of transferases specifically those transferring one-carbon group methyltransferases.
