Circular symmetry of the light-harvesting 1 complex from Rhodospirillum rubrum is not perturbed by interaction with the reaction center

Research demonstrates that stabilization of the circular symmetric arrangement of the bacteriochlorophyll pigments is mediated by the interaction of the reaction center with the light harvesting complex 1 as determined by single molecule microscopy, cryoelectronmicroscopy and atomic force microscopy. Data show an elliptical distortion of the light harvesting complex 1 induced by the reaction center.
