Clostridium carboxidivorans Strain P7T Recombinant Formate Dehydrogenase Catalyzes Reduction of CO2 to Formate

摘要

Recombinant formate dehydrogenase from the acetogen Clostridium carboxidivorans strain P7T, expressed in Escherichia coli, shows particular activity towards NADH-dependent carbon dioxide reduction to formate due to the relative binding affinities of the substrates and products. The enzyme retains activity over 2 days at 4°C under oxic conditions.
