IUBMB Enzyme Nomenclature


Accepted name: 3-hydroxybenzoate 6-monooxygenase

Reaction: 3-hydroxybenzoate + NADH + H+ + O2 = 2,5-dihydroxybenzoate + NAD+ + H2O

Other name(s): 3-hydroxybenzoate 6-hydroxylase; m-hydroxybenzoate 6-hydroxylase; 3-hydroxybenzoic acid-6-hydroxylase

Systematic name: 3-hydroxybenzoate,NADH:oxygen oxidoreductase (6-hydroxylating)

Comments: A flavoprotein (FAD). Acts also on a number of analogues of 3-hydroxybenzoate substituted in the 2, 4, 5 and 6 positions; NADPH can act instead of NADH, but more slowly.
