ndhH1

Gene
ndhH1
Protein
NAD(P)H-quinone oxidoreductase subunit H 1
Organism
Gloeobacter violaceus (strain ATCC 29082 / PCC 7421)
Length
393 amino acids
Function
NDH-1 shuttles electrons from an unknown electron donor, via FMN and iron-sulfur (Fe-S) centers, to quinones in the respiratory and/or the photosynthetic chain. The immediate electron acceptor for the enzyme in this species is believed to be plastoquinone. Couples the redox reaction to proton translocation, and thus conserves the redox energy in a proton gradient. Cyanobacterial NDH-1 also plays a role in inorganic carbon-concentration.
Similarity
Belongs to the complex I 49 kDa subunit family.
Mass
45.016 kDa
