| Outline of Final Research Achievements |
The aim of this study is to evaluate the proteorhodopsin-mediated sunlight energy flow. In the beginning of the study, proteorhodopsin (PR) was the only type 1 rhodopsin found in marine bacteria. Therefore, the first research plan was designed only for the proteorhodopsin-mediated phototrophy. However, novel type 1 rhodopsins, such as sodium ion pumping rhodopsin (NaR) and chloride ion pumping rhodopsin (ClR), were discovered in marine flavobacteria by the genomic analysis and reported by our group during the research period. This result shows the ways of rhodopsin-mediated light utilization are more diverse than previously thought. In the future, investigating the light use efficiency of each rhodopsin is needed for the evaluation of the rhodopsin-mediated sunlight energy flow.
