| Name |
4-hydroxybenzoate 3-monooxygenase [NAD(P)H];
4-hydroxybenzoate 3-monooxygenase (reduced nicotinamide adenine
dinucleotide (phosphate));
4-hydroxybenzoate-3-hydroxylase;
4-hydroxybenzoate 3-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

| Comment |
A flavoprotein (FAD). The enzyme from Corynebacterium cyclohexanicum
is highly specific for 4-hydroxybenzoate, but uses NADH and NADPH at
approximately equal rates (cf. EC 1.14.13.2 4-hydroxybenzoate
3-monooxygenase). It is less specific for NADPH than EC 1.14.13.2. |
