2-hydroxy-1,4-benzoquinone reductase

Class of enzymes 2-hydroxy-1,4-benzoquinone reductase 1.6.5.7 0050625 2-hydroxy-1,4-benzoquinone reductase (1.6.5.7) is an enzyme that catalyzes the chemical reaction 40% hydroxy-1,4-benzoquinone + NADH reversible H+ H+ hydroxyquinol + NAD+ The three substrates of this enzyme are hydroxy-1,4-benzoquinone, reduced nicotinamide adenine dinucleotide (NADH), and a proton. Its products are hydroxyquinol and oxidised NAD+.1.6.5.7 Zaborina O, Daubaras DL, Zago A, Xun L, Saido K, Klem T, Nikolic D, Chakrabarty AM Novel pathway for conversion of chlorohydroxyquinol to maleylacetate in Burkholderia cepacia AC1100 Journal of Bacteriology 180 17 4667–75 September 1998 10.1128/JB.180.17.4667-4675.1998 9721310 107482 This enzyme participates in the metabolism of 2,4,5-trichlorophenoxyacetic acid in the bacteria Burkholderia cepacia. Nomenclature This enzyme belongs to the family of oxidoreductases, specifically those acting on NADH or NADPH with a quinone or similar compound as acceptor. The systematic name of this enzyme class is 2-hydroxy-1,4-benzoquinone:NADH oxidoreductase. Other names in common use include hydroxybenzoquinone reductase, 1,2,4-trihydroxybenzene:NAD oxidoreductase, and NADH:2-hydroxy-1,4-benzoquinone oxidoreductase.
