  • Proton-transport vesicle having reconstituted heterologous photosensitive proteins and method for preparing same
    Patent number: 10421793
    Abstract: The present invention relates to a proton-transport vesicle and a method for preparing the same, the proton-transfer vesicle comprising: (a) a single phospholipid bilayer liposome; (b) a rhodopsin protein; and (c) a photosystem II protein, wherein the rhodopsin protein and the photosystem II protein are inserted and located in a bilayer of the liposome. Since the heterologous photosensitive proteins are inserted and located in the bilayer of the liposome, the vesicle has an absorption wavelength band of the whole region of visible light by utilizing absorption bands of different lights of the respective photosensitive proteins. Thus, the restricted efficiency caused by utilizing only a specific wavelength in existing organisms or artificial vesicles was improved, and the wavelength region can be enlarged to the all wavelength ranges of visible light.
