| 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. |
| Other Notes: | For life science research only. Not for use in diagnostic procedures. |
| Quality: | Contaminants: <0.005% LDH and ADH each, <0.1% MDH |
| 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. |
| 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. |
