CATH Classification

Domain Context

CATH Clusters

Superfamily FAD/NAD(P)-binding domain
Functional Family p-hydroxybenzoate hydroxylase

Enzyme Information

1.14.13.2
4-hydroxybenzoate 3-monooxygenase.
based on mapping to UniProt P00438
4-hydroxybenzoate + NADPH + O(2) = protocatechuate + NADP(+) + H(2)O.
-!- Most enzymes from Pseudomonas are highly specific for NAD(P)H (cf. EC 1.14.13.33).
