Tetrahydrocolumbamine 2-O-methyltransferase

In enzymology, a tetrahydrocolumbamine 2-O-methyltransferase (EC number|2.1.1.89) is an enzyme that catalyzes the chemical reaction

:S-adenosyl-L-methionine + 5,8,13,13a-tetrahydrocolumbamine $ightleftharpoons$ S-adenosyl-L-homocysteine + tetrahydropalmatine

Thus, the two substrates of this enzyme are S-adenosyl methionine and 5,8,13,13a-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. The systematic name of this enzyme class is S-adenosyl-L-methionine:5,8,13,13a-tetrahydrocolumbamine 2-O-methyltransferase. This enzyme is also called tetrahydrocolumbamine methyltransferase. This enzyme participates in alkaloid biosynthesis i.
