| Abstract/Contents: | "The influence of respiration on photosythetic electron transport were investigated in the wild type and psaB mutants from Synechocystis sp. PCC6803. The amount of glucose uptake in the wild type was proportional to the glucose concentration added in wild type and less than that of psaB mutants in the dark. It was suggested that psaB mutants more depend on the glucose than the wild type. It was investigated how the activities of isocitrate dehydrogenase(IDH) and glucose-6-phosphate dehydrogenase(G6PDH) were changed. The activities of IDH were very low. While, the activities of G6PDH were much higher than that of IDH. These results agree to the reports that exogenous glucose was dismilated aerobically via Oxidative Pentose Phosphate Pathway in heterotrophic cyanobacteria. PsaB mutants showed high G6PDH activity in the presence of glucose as well as in the dark and high respiratory activities especially in the dark. It was also investigated how photosynthetic electron transport activities than wild type in the presence of glucose as well as in the dark. In the results, it was proposed that photosynthetic electron transport between PS I and PS II was complemented by respiratory electron transport through the NADPH generated by Oxidative Pentose Phophate Pathway in psaB mutant from Synechocystis sp. PCC6803." |
