Protein

NAD(P)H-quinone oxidoreductase subunit 2

Gene

ndhB

Organism
Synechocystis sp. (strain PCC 6803 / Kazusa)
Status
Reviewed - Annotation score: 3 out of 5- Protein inferred from homologyi

Functioni

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.UniRule annotation

Catalytic activityi

NAD(P)H + plastoquinone = NAD(P)+ + plastoquinol.UniRule annotation
