抄録

The kinetic properties of the conversion of CO₂ to formic acid with formate dehydrogenase (FDH) using some dithionite-reduced 2,2′-bipyridinium salts (1,1′-ethylene-2,2′-bipyridinium dibromide diquat and 1,1′-dimethyl-2,2′-bipyridinium dichloride) as an artificial coenzyme were studied. By using the reduced form of diquat, the effective CO₂ reduction to formic acid with FDH is accomplished. The catalytic efficiency, the k_cat/K_m value of the reduced form of diquat was ca. 126 times larger than that of NADH.
