==Overview==

Desulfovibrio gigas formate dehydrogenase is the first representative of a, tungsten-containing enzyme from a mesophile that has been structurally, characterized. It is a heterodimer of 110 and 24 kDa subunits. The large, subunit, homologous to E. coli FDH-H and to D. desulfuricans nitrate, reductase, harbors the W site and one [4Fe-4S] center. No small subunit, ortholog containing three [4Fe-4S] clusters has been reported. The, structural homology with E. coli FDH-H shows that the essential residues, (SeCys158, His159, and Arg407) at the active site are conserved. The, active site is accessible via a positively charged tunnel, while product, release may be facilitated, for H(+) by buried waters and protonable amino, acids and for CO(2) through a hydrophobic channel.
