formylmethanofuran dehydrogenase;
formylmethanofuran:acceptor oxidoreductase
Acting on the aldehyde or oxo group of donors;
With an iron-sulfur protein as acceptor
formylmethanofuran:ferredoxin oxidoreductase
a formylmethanofuran + H2O + 2 oxidized ferredoxin [iron-sulfur] cluster = CO2 + a methanofuran + 2 reduced ferredoxin [iron-sulfur] cluster + 2 H+ [RN:R11743]
R11743 > R03015;
(other) R08060
formylmethanofuran [CPD:C01001];
H2O [CPD:C00001];
oxidized ferredoxin [iron-sulfur] cluster [CPD:C00139]
CO2 [CPD:C00011];
methanofuran [CPD:C00862];
reduced ferredoxin [iron-sulfur] cluster [CPD:C00138];
H+ [CPD:C00080]
Contains a molybdopterin cofactor and numerous [4Fe-4S] clusters. In some organisms an additional subunit enables the incorporation of tungsten when molybdenum availability is low. The enzyme catalyses a reversible reaction in methanogenic archaea, and is involved in methanogenesis from CO2 as well as the oxidation of coenzyme M to CO2. The reaction is endergonic, and is driven by coupling with the soluble CoB-CoM heterodisulfide reductase via electron bifurcation.
