In [[Biology:Enzymology|enzymology]], a '''6-O-methylnorlaudanosoline 5'-O-methyltransferase''' ({{EC number|2.1.1.121}}) is an [[Biology:Enzyme|enzyme]] that [[Chemistry:Catalysis|catalyzes]] the [[Chemistry:Chemical reaction|chemical reaction]]

:S-adenosyl-L-methionine + 6-O-methylnorlaudanosoline <math>\rightleftharpoons</math> S-adenosyl-L-homocysteine + nororientaline

Thus, the two [[Biology:Substrate (biochemistry)|substrates]] of this enzyme are [[Chemistry:S-Adenosyl methionine|S-adenosyl methionine]] and 6-O-methylnorlaudanosoline, whereas its two [[Chemistry:Product|products]] are S-adenosylhomocysteine and nororientaline.

This enzyme belongs to the family of [[Biology:Transferase|transferase]]s, specifically those transferring one-carbon group methyltransferases.  The [[Biology:List of enzymes|systematic name]] of this enzyme class is '''S-adenosyl-L-methionine:6-O-methylnorlaudanosoline 5'-O-methyltransferase'''. This enzyme participates in alkaloid biosynthesis i.
