Entry Name (RS)-norcoclaurine 6-O-methyltransferase
Class Transferases;BRITE hierarchy
Sysname S-adenosyl-L-methionine:(RS)-norcoclaurine 6-O-methyltransferase
Reaction(IUBMB) S-adenosyl-L-methionine + (RS)-norcoclaurine = S-adenosyl-L-homocysteine + (RS)-coclaurine [RN:
R05162 ]
Reaction(KEGG) Substrate S-adenosyl-L-methionine [CPD:
C00019 ];
(R,S)-norcoclaurine [CPD:
C06346 ]
Product S-adenosyl-L-homocysteine [CPD:
C00021 ];
(R,S)-coclaurine [CPD:
C06348 ]
Comment 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.
