== Publication Abstract from PubMed ==
 +
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.

[[http://www.uniprot.org/uniprot/FDHA_DESGI FDHA_DESGI]] Alpha chain of the formate dehydrogenase (FDH) catalyze the reversible two-electron oxidation of formate to carbon dioxide. FDH loses activity in the presence of air, but this activity can be restored. The alpha subunit of formate dehydrogenase forms the active site. [[http://www.uniprot.org/uniprot/FDHB_DESGI FDHB_DESGI]] Beta chain of the formate dehydrogenase (FDH) catalyzes the reversible two-electron oxidation of formate to carbon dioxide. FDH loses activity in the presence of air, but this activity can be restored. This chain is an electron transfer unit.
