EC 2.1.1.352

Names

Accepted name:
3-O-acetyl-4'-O-demethylpapaveroxine 4'-O-methyltransferase
Systematic name:
S-adenosyl-L-methionine:3-O-acetyl-4'-O-demethylpapaveroxine 4'-O-methyltransferase

Reaction

Comments:

This activity is part of the noscapine biosynthesis pathway, as characterized in the plant Papaver somniferum (opium poppy). It is catalysed by heterodimeric complexes of the OMT2 gene product and the product of either OMT3 or 6OMT. OMT2 is the catalytic subunit in both complexes.
