ADG92402.1 | NADH ubiquinone oxidoreductase 20 kDa subunit; COGs: COG3260 Ni Fe-hydrogenase III small subunit; InterPro IPR006137:IPR006138; KEGG: cco:CCC13826_0713 hydrogenase-4 component I; PFAM: NADH ubiquinone oxidoreductase 20 kDa subunit; SPTR: A7ZBL5 Hydrogenase-4 component I; PFAM: NADH ubiquinone oxidoreductase, 20 Kd subunit.

nuoB | NADH-quinone oxidoreductase, B subunit; 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.
