| Research Abstract |
Thylakoid and photosynthetic bacterial membranes possess three-dimensional multi-layered structures. These membranes efficiently captured transfer light energy. In order to reveal the three-dimensional structure-function relationship, we constructed multi-layered planar membrane containing photosynthesis antenna complex (LH2). Bicelles containing biotinyl lipids were tethered to a planar lipid bilayer via avidin-biotin interaction. Upon detergent removal, transformation from bicelle to planar membrane took place to form layered planar bilayer. The layered structure was observed by atomic force microscopy (AFM). Multi-layered membranes containing LH2 complex was also constructed by use of LH2-reconstituted bicelles. Thus, we successfully constructed artificial thylakoid membranes.
