IntEnz Enzyme Nomenclature
EC 2.1.1.128

Names

Accepted name:
(RS)-norcoclaurine 6-O-methyltransferase
Systematic name:
S-adenosyl-L-methionine:(RS)-norcoclaurine 6-O-methyltransferase

Reactions

Comments:

The enzyme will also catalyse the 6-O-methylation of (RS)-norlaudanosoline to form 6-O-methyl-norlaudanosoline, but this alkaloid has not been found to occur in plants.
