Protein attributes

Sequence length	270 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
Protein existence	Evidence at transcript level.

General annotation (Comments)

Function	Catalyzes the reversible oxidation of CO2 and methanofuran (MFR) to N-formylmethanofuran (CHO-MFR). Can only oxidize formylmethanofuran. This enzyme is oxygen-labile.
Catalytic activity	Formylmethanofuran + H2O + acceptor = CO2 + methanofuran + reduced acceptor.
Cofactor	Tungsten.
Pathway	One-carbon metabolism; methanogenesis from carbone dioxide; 5,10-methenyl-H(4)MPT from CO(2): step 1/3.
Subunit structure	This enzyme is composed of seven subunits fwdA (65 kDa), fwdB (53 kDa), fwdC (31 kDa), fwdD (15 kDa), fwdE, fwdF and fwdG By similarity.
Induction	By growth on tungsten or molybdenum under anaerobic conditions.
Sequence similarities	Belongs to the fwdC/fmdC family.
