the enzyme is involved in the reduction of heterodisulfide
physiological function
the FqoF protein forms the input device of the protein complex which oxidizes coenzyme F420H2. Thus, this polypeptide replaces the NADH-oxidizing module of NADH dehydrogenases of bacteria which are not found in Archaeoglobus fulgidus. Then the electrons are channeled to the membrane-associated fragment composed of FqoBCDI, which is homologous to the corresponding module of complex I. As the subunits FqoAHJKLMN are highly hydrophobic and are related to polypeptides comprising the membrane fragment of complex I, they may form the membrane-integral module of the F420H2:quinone oxidoreductase that is responsible for the reduction of a special menaquinone found in the cytoplasmic membrane of Archaeoglobus fulgidus
