Zusammenfassung:
The iron (Fe) proteins of molybdenum (Mo) and vanadium (V) nitrogenases mimic carbon monoxide (CO) dehydrogenase in catalyzing the interconversion between CO2 and CO under ambient conditions. Catalytic reduction of CO2 to CO is achieved in vitro and in vivo upon redox changes of the Fe-protein associated [Fe4S4] clusters. These observations establish the Fe protein as a model for investigation of CO2 activation while suggesting its biotechnological adaptability for recycling the greenhouse gas into useful products.
