NQO1

Gene
nqo1
Protein
NADH-quinone oxidoreductase subunit 1
Organism
Thermus thermophilus (strain HB8 / ATCC 27634 / DSM 579)
Length
438 amino acids
Function
NDH-1 shuttles electrons from NADH, via FMN and iron-sulfur (Fe-S) centers, to quinones in the respiratory chain. The immediate electron acceptor for the enzyme in this species is menaquinone. Couples the redox reaction to proton translocation (for every two electrons transferred, four hydrogen ions are translocated across the cytoplasmic membrane), and thus conserves the redox energy in a proton gradient required for the synthesis of ATP. The Nqo1 subunit contains the NADH-binding site and the primary electron acceptor FMN.
Similarity
Belongs to the complex I 51 kDa subunit family.

48.632 kDa

Length
431 amino acids
Function
NDH-1 shuttles electrons from NADH, via FMN and iron-sulfur (Fe-S) centers, to quinones in the respiratory chain. The immediate electron acceptor for the enzyme in this species is believed to be ubiquinone. Couples the redox reaction to proton translocation (for every two electrons transferred, four hydrogen ions are translocated across the cytoplasmic membrane), and thus conserves the redox energy in a proton gradient.

Gene
NQO1
Protein
NAD(P)H dehydrogenase [quinone] 1
Organism
Cavia porcellus
Length
275 amino acids
Function
The enzyme apparently serves as a quinone reductase in connection with conjugation reactions of hydroquinons involved in detoxification pathways as well as in biosynthetic processes such as the vitamin K-dependent gamma-carboxylation of glutamate residues in prothrombin synthesis.
Similarity
Belongs to the NAD(P)H dehydrogenase (quinone) family.
