General description

Formate:NAD+ oxidoreductase
Formate dehydrogenase is part of the D-specific 2-hydroxy acid superfamily of dehydrogenases. It is a dimer of two identical subunits. The enzyme has a cysteine residue which is essential for its activity or structural integrity.

Specificity

Substrate Specificity and Km:
Formate dehydrogenase reacts only with formate (Km = 13 mM at 30 °C and pH 7.5; 11 mM at 25 °C and pH 7.5) and NAD (Km 0.09 mM; 30 °C; pH 7.5). It does not react with acetate, oxalate, lactate, succinate, propionate or ascorbate, nor will the enzyme reduce NADP.

Application

Most widely used in cofactor recycling systems for NADH.

Quality

Contaminants: <0.005% LDH and ADH each, <0.1% MDH

Unit Definition

One unit (U) formate dehydrogenase will oxidize 1 μmol of formic acid to CO2 in 1 minute at +25 °C and pH 7.6. The above assay produces 1 mmol of NADH per mmol of formate oxidized.

Storage and Stability

Store dry

The understanding of the mechanism of enzymatic recovery of NADH is of biological and of considerable biotechnological interest, since the essential, but expensive, cofactor NADH is exhausted in asymmetric hydrogenation processes, but can be recovered by NAD(+)-dependent formate dehydrogenase (FDH).

The standard diagnostic approach to methanol poisoning is chromatographic measurement of methanol on centrally placed stationary equipment. Methanol poisoning in places where such equipment is unavailable is thus often not diagnosed. Methanol is metabolized to a toxic metabolite, formate; the
