BRITE hierarchy
Sysname
4-hydroxybenzoate,NAD(P)H:oxygen oxidoreductase (3-hydroxylating)
Reaction(IUBMB)
4-hydroxybenzoate + NAD(P)H + H+ + O2 = 3,4-dihydroxybenzoate + NAD(P)+ + H2O [RN:R01296 R01298]
Reaction(KEGG)
Substrate

NADH [CPD:C00004];
NADPH [CPD:C00005];
H+ [CPD:C00080];
O2 [CPD:C00007]
Product
3,4-dihydroxybenzoate [CPD:C00230];
NAD+ [CPD:C00003];
NADP+ [CPD:C00006];

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.
