英文摘要
Archaeal-type rhodopsins were found in Archaea, but the recent genome sequencing projects have revealed that archaeal rhodopsins also exist in Eukarya and Eubacteria. In this grant project, we investigated molecular mechanism of light-energy and light-signal conversions in newly discovered archaeal-type rhodopsins. Comprehensive Fourier-transform infrared (FTIR) analysis led to a finding that proton-pumping rhodopsins possess strongly hydrogen-bonded water molecules, suggesting that such an internal water is the functional determinant of light-driven proton pump.
