Systematic name: |
S-adenosyl-L-methionine:3′-hydroxy-N-methyl-(S)-coclaurine 4′-O-methyltransferase |
Comments: |
Involved in isoquinoline alkaloid metabolism in plants. The enzyme has also been shown to catalyse the methylation of (RS)-laudanosoline, (S)-3′-hydroxycoclaurine and (RS)-7-O-methylnorlaudanosoline. |
