CC   -!- FUNCTION: Alternative, nonproton pumping NADH:quinone oxidoreductase
CC       that delivers electrons to the respiratory chain by oxidation of NADH
CC       and reduction of quinones, and contributes to the regeneration of
CC       NAD(+). {ECO:0000250|UniProtKB:Q2FZV7}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=a quinone + H(+) + NADH = a quinol + NAD(+);
CC         Xref=Rhea:RHEA:46160, ChEBI:CHEBI:15378, ChEBI:CHEBI:24646,
CC         ChEBI:CHEBI:57540, ChEBI:CHEBI:57945, ChEBI:CHEBI:132124; EC=1.6.5.9;
CC         Evidence={ECO:0000250|UniProtKB:Q2FZV7};
CC   -!- COFACTOR:
CC       Name=FAD; Xref=ChEBI:CHEBI:57692;
CC         Evidence={ECO:0000250|UniProtKB:Q2FZV7};
CC       Note=Binds 1 FAD per subunit. {ECO:0000250|UniProtKB:Q2FZV7};
CC   -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000250|UniProtKB:Q2FZV7}.
CC   -!- SIMILARITY: Belongs to the NADH dehydrogenase family. {ECO:0000305}.
