Experimental Technique/Method:X-RAY DIFFRACTION Resolution:2.2 Classification:PHOTOSYNTHESIS Release Date:2017-09-06 Deposition Date:2017-03-22 Revision Date:2017-09-20#2017-09-27 Molecular Weight:97897.33 Macromolecule Type:Protein Residue Count:625 Atom Site Count:6719 DOI:10.2210/pdb5v8k/pdb Abstract: Reaction centers are pigment-protein complexes that drive photosynthesis by converting light into chemical energy. It is believed that they arose once from a homodimeric protein. The symmetry of a homodimer is broken in heterodimeric reaction-center structures, such as those reported previously. The 2.2-angstrom resolution x-ray structure of the homodimeric reaction center-photosystem from the phototroph
