Caffeate O-methyltransferase
In enzymology, a caffeate O-methyltransferase is an enzyme that catalyzes the chemical reaction
Thus, the two substrates of this enzyme are S-adenosyl methionine and 3,4-dihydroxy-trans-cinnamate, whereas its two products are S-adenosylhomocysteine and 3-methoxy-4-hydroxy-trans-cinnamate.
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:3,4-dihydroxy-trans-cinnamate 3-O-methyltransferase. Other names in common use include caffeate methyltransferase, caffeate 3-O-methyltransferase, and S-adenosyl-L-methionine:caffeic acid-O-methyltransferase. This enzyme participates in phenylpropanoid biosynthesis.As of late 2007, two structures have been solved for this class of enzymes, with PDB accession codes and.
