Formilmetanofuran dehidrogenaza (EC 1.2.99.5, formilmethanofuran:(akceptor) oksidoreduktaza) je enzim sa sistematskim imenom formilmethanofuran:akceptor oksidoreduktaza.[1][2][3][4] Ovaj enzim katalizuje sledeću hemijsku reakciju
- formilmetanofuran + H2O + akceptor CO2 + metanofuran + redukovani akceptor
Ovaj molibdoprotein sadrži pterinski kofactor. Volfram može da zameni molibden. Ovaj enzim katalizuje reverzibilnu reakciju u metanogenim bakterijama, i učestvuje u metanogenezi iz CO2 kao i oksidaciji metil-koenzima M do CO2. Metil viologen može da deluje kao akceptor. Ovaj enzim takođe oksiduje N-furfurilformamid.
