Outline of Final Research Achievements

We found methanogenic archaeal RuBisCO functions in the novel CO2 fixation pathway which has some different steps from the photosynthetic Calvin cycle, suggesting that this novel pathway should be the ancient Calvin cycle. Enzymatic analysis of hybrid RuBisCO created by swap of large and small subunits between thermophilic cyanobacteria RuBisCO with high CO2 specificity and mesophilic cyanobacteria RuBisCO revealed that small subunit was involved in CO2 specificity. Transplastomic tobacco with over expression of RuBisCO activase tends to be enhanced a photosynthetic CO2 fixation rate.
