IUBMB Enzyme Nomenclature


Accepted name: resorcinol 4-hydroxylase (NADPH)

Reaction: resorcinol + NADPH + H+ + O2 = hydroxyquinol + NADP+ + H2O

Glossary: resorcinol = 1,3-dihydroxybenzene
hydroxyquinol = 1,2,4-trihydroxybenzene

Systematic name: resorcinol,NADPH:oxygen oxidoreductase (4-hydroxylating)

Comments: The enzyme, characterized from the bacterium Corynebacterium glutamicum, is a single-component hydroxylase. The enzyme has no activity with NADH. cf. EC, resorcinol 4-hydroxylase (NADH), and EC, resorcinol 4-hydroxylase (FADH2).
