6-O-methylnorlaudanosoline 5'-O-methyltransferase
In enzymology, a 6-O-methylnorlaudanosoline 5'-O-methyltransferase () is an enzyme that catalyzes the chemical reaction Thus, the two substrates of this enzyme are S-adenosyl methionine and 6-O-methylnorlaudanosoline, whereas its two products are S-adenosylhomocysteine and nororientaline. 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:6-O-methylnorlaudanosoline 5'-O-methyltransferase. This enzyme participates in alkaloid biosynthesis i.
