Response of NAD(P)H dehydrogenase complex to the alteration of CO2 concentration in the cyanobacterium Synechocystis PCC6803

An NADPH-specific NDH-1 sub-complex was separated by native-polyacrylamide gel electrophoresis and detected by activity staining from the whole cell extracts of Synechocystis PCC6803. Low CO2 caused an increase in the activity of this sub-complex quickly, accompanied by an evident increase in the ex...

Zusammenfassung:An NADPH-specific NDH-1 sub-complex was separated by native-polyacrylamide gel electrophoresis and detected by activity staining from the whole cell extracts of Synechocystis PCC6803. Low CO2 caused an increase in the activity of this sub-complex quickly, accompanied by an evident increase in the expression of NdhK and PSI-driven NADPH oxidation activity that can reflect the activity of NDH-1-mediated cyclic electron transport. During incubation with high CO2, the activities of NDH-1 sub-complex and PSI-driven NADPH oxidation as well as the protein level of NdhK slightly increased at the beginning, but decreased evidently in various degrees along with incubation time. These results suggest that CO2 concentration in vitro as a signal can control the activity of NDH-1 complex, and NDH-1 complex may in turn function in the regulation of CO2 uptake
