CC   -!- FUNCTION: Catalyzes the reversible oxidation of CO(2) and
CC       methanofuran (MFR) to N-formylmethanofuran (CHO-MFR). This enzyme
CC       is oxygen-labile. May function as an electron transfer protein (By
CC       similarity).
CC   -!- CATALYTIC ACTIVITY: Formylmethanofuran + H(2)O + acceptor = CO(2)
CC       + methanofuran + reduced acceptor.
CC   -!- COFACTOR: Binds 2 4Fe-4S clusters (Potential).
CC   -!- ENZYME REGULATION: Not inactivated by cyanide (By similarity).
CC   -!- PATHWAY: One-carbon metabolism; methanogenesis from carbone
CC       dioxide; 5,10-methenyl-H(4)MPT from CO(2): step 1/3.
CC   -!- INDUCTION: By growth on tungsten or molybdenum under anaerobic
CC       conditions.
CC   -!- SIMILARITY: Contains 2 4Fe-4S ferredoxin-type domains.
