DE   4-hydroxybenzoate 3-monooxygenase (NAD(P)H).
AN   4-hydroxybenzoate 3-hydroxylase.
CA   4-hydroxybenzoate + NAD(P)H + O(2) = 3,4-dihydroxybenzoate + NAD(P)(+) +
CA   H(2)O.
CF   FAD.
CC   -!- The enzyme from Corynebacterium cyclohexanicum is highly specific for
CC       4-hydroxybenzoate, but uses NADH and NADPH at approximately equal
CC       rates (cf. EC 1.14.13.2).
CC   -!- It is less specific for NADPH than EC 1.14.13.2.
