Comments [?]

case <OG:Chloroplast>
Function NDH shuttles electrons from NAD(P)H:plastoquinone, via FMN and iron-sulfur (Fe-S) centers, to quinones in the photosynthetic chain and possibly in a chloroplast respiratory 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.
else case <OC:Cyanobacteria>
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.
else case <OC:Methanomicrobia>
Function FPO shuttles electrons from F(420)H(2), via FAD and iron-sulfur (Fe-S) centers, to quinones in the F(420)H(2):heterodisulfide oxidoreduction chain. The immediate electron acceptor for the enzyme in this species is believed to be methanophenazine. Couples the redox reaction to proton translocation (for every two electrons transferred, 0.9 hydrogen ions are translocated across the cytoplasmic membrane), and thus conserves the redox energy in a proton gradient.
else case <OC:Mycobacterium> or <OC:Rhodothermus>
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 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.
else
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. This subunit may bind ubiquinone.

Comments 14 proteins form the NDH-1 complex in most bacteria whereas only 11 genes are encoded in cyanobacteria and chloroplast genomes, and 12 in archea. THET8 and PARDE are annotated with an other nomenclature. See: MEDLINE=95317406; PubMed=7796904; DOI=10.1016/0014-5793(95)00548-N; Friedrich T., Steinmuller K., Weiss H.; "The proton-pumping respiratory complex I of bacteria and mitochondria and its homologue in chloroplasts."; FEBS Lett. 367:107-111(1995). See: MEDLINE=98115918; PubMed=9448329; Sazanov L.A., Burrows P.A., Nixon P.J.; "The plastid ndh genes code for an NADH-specific dehydrogenase: isolation of a complex I analogue from pea thylakoid membranes."; Proc.
