In enzymology, a columbamine O-methyltransferase (EC 2.1.1.118) is an enzyme that catalyzes the chemical reaction
- S-adenosyl-L-methionine + columbamine S-adenosyl-L-homocysteine + palmatine
Thus, the two substrates of this enzyme are S-adenosyl methionine and columbamine, whereas its two products are S-adenosylhomocysteine and palmatine.
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:columbamine O-methyltransferase. This enzyme participates in alkaloid biosynthesis i.
