With a quinone or similar compound as acceptor
BRITE hierarchy
Sysname
NADH:2-hydroxy-1,4-benzoquinone oxidoreductase
Reaction(IUBMB)
2-hydroxy-1,4-benzoquinone + NADH + H+ = hydroxyquinol + NAD+ [RN:R05399]
Reaction(KEGG)
Substrate
2-hydroxy-1,4-benzoquinone [CPD:C07103];
NADH [CPD:C00004];
H+ [CPD:C00080]
Product
hydroxyquinol [CPD:C02814];
NAD+ [CPD:C00003]
Comment
A flavoprotein (FMN) that differs in substrate specificity from other quinone reductases. The enzyme in Burkholderia cepacia is inducible by 2,4,5-trichlorophenoxyacetate.
