| Name |
protopine 6-monooxygenase;
protopine 6-hydroxylase |
| Class |
Oxidoreductases;
Acting on paired donors, with O2 as oxidant and incorporation or
reduction of oxygen. The oxygen incorporated need not be derived
from O2;
With NADH or NADPH as one donor, and incorporation of one atom of
oxygen into the other donor
