naringenin,2-oxoglutarate:oxygen oxidoreductase (3-hydroxylating) |
| 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 2-oxoglutarate as one donor, and incorporation of one atom of
oxygen into each donor
