PFAM accession number:PF00346
Interpro abstract (IPR001135):

This entry represents the subunit D (NuoD) of NADH-quinone oxidoreductase (EC and the subunit H (NdhH) of NAD(P)H-quinone oxidoreductase (EC 1.6.5.-). NADH-quinone (Q) oxidoreductase is a large and complex redox proton pump, which utilises the free energy derived from oxidation of NADH with lipophilic electron/proton carrier Q to translocate protons across the membrane to generate an electrochemical proton gradient [(PUBMED:11695831)]. Subunit D (NuoD) is a 49kDa polypeptide that appears to be evolutionarily important in determining the physiological function of complex I/NDH-1 [(PUBMED:11695831)].

GO process:oxidation-reduction process (GO:0055114)
GO function:quinone binding (GO:0048038), NAD binding (GO:0051287), oxidoreductase activity, acting on NAD(P)H (GO:0016651)
