Formate dehydrogenase consists of two transmembrane domains; three α-helices of the β-subunit and four transmembrane helices from the gamma-subunit. The β-subunit of formate dehydrogenase is present in the periplasm with a single transmembrane α-helix spanning the membrane by anchoring the β-subunit to the inner-membrane surface. The β-subunit has two subdomains, where each subdomain has two [4Fe-4S] ferredoxin clusters. T… Formate salts have the formula M(O2CH)(H2O)x. Such salts are prone to decarboxylation. For example, hydrated nickel formate decarboxylates at about 200 °C with reduction of the Ni to finely powdered nickel metal: Ni(HCO2)2(H2O)2 → Ni + 2 CO2 + 2 H2O + H2 Such fine powders are useful as hydrogenation catalysts.
