摘要The low-resolution shape of the integral membrane protein light-harvesting complex LH2 from photosynthetic bacteria Rhodobacter sphaeroides 2. 4. 1 in detergent solution has been determined from synchrotron small-angle X-ray scattering ( SAXS) data using directly curve fitting by an ellipsoid and ab initio shape determination method of multipole expansion respectively. The results indicate that the LH2 proteins in aqueous solution has a shape of oblate plate. In contrast to the perfect symmetrical ring-like structure of LH2 in crystalline, the molecular shape of the LH2 complex in detergent solution clearly deviates from the ring-like crystal structure, which is consistent with the result of single molecular spectroscopy study of the isolated single LH2 molecules.
