Accepted name: |
caffeate O-methyltransferase |
Reaction: |
S-adenosyl-L-methionine + 3,4-dihydroxy-trans-cinnamate = S-adenosyl-L-homocysteine + 3-methoxy-4-hydroxy-trans-cinnamate |
Other name(s): |
caffeate methyltransferase; caffeate 3-O-methyltransferase; S-adenosyl-L-methionine:caffeic acid-O-methyltransferase |
Systematic name: |
S-adenosyl-L-methionine:3,4-dihydroxy-trans-cinnamate 3-O-methyltransferase |
Comments: |
3,4-Dihydroxybenzaldehyde and catechol can act as acceptors, but more slowly. |
