- 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.
