摘要：

The effects of isotope-labelled NADH and CO2 on formate dehydrogenase from Candida boidinii (CbFDH)-catalyzed CO2 reduction activity were investigated. It was found that the rate of CO2 reduction to formate with CbFDH decreased by using deuterium-labelled NADH (NADH-d(4)) as a co-enzyme. In contrast, the rate of CbFDH-catalyzed CO2 reduction to formate was unchanged in the use of (CO2)-C-13 as a substrate. In the substrate (CO2)-C-12 and (CO2)-C-13 is mixed, however, curious phenomenon on CbFDH-catalyzed CO2 reduction activity decrease was observed.
