CC -!- FUNCTION: Formate dehydrogenase allows the bacterium to use formate as
CC major electron donor during anaerobic respiration, when nitrate is used
CC as electron acceptor. Subunit gamma is the cytochrome b556 component of
CC the formate dehydrogenase-N, and also contains a menaquinone reduction
CC site that receives electrons from the beta subunit (FdnH), through its
CC hemes. Formate dehydrogenase-N is part of a system that generates
CC proton motive force, together with the dissimilatory nitrate reductase
CC (Nar) (By similarity). {ECO:0000250}.
CC -!- COFACTOR:
CC Name=heme; Xref=ChEBI:CHEBI:30413; Evidence={ECO:0000250};
CC Note=Binds 2 heme groups per subunit. Heme 1 is located at the
CC cytoplasmic interface, heme 2 is located at the periplasmic interface.
CC Electrons are transferred from the periplasmic to the cytoplasmic heme.
CC {ECO:0000250};
CC -!- SUBUNIT: Trimer of heterotrimers, consisting of subunits alpha, beta
CC and gamma. {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Cell inner membrane {ECO:0000250}; Multi-pass
CC membrane protein {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the formate dehydrogenase gamma subunit family.
CC {ECO:0000305}.
