 2C9O RIGID BODY FIT ADP_EM
Protocol: Rigid Body and refinement using a Powell base minimization. Rigid-body fitting was performed using ADP_EM. From the best scores found, we carried out an additional refinement step by freely moving a single monomer using a multidimensional Powel optimization routine. Subsequently, 6-fold rotational symmetry was applied to the refined monomer to complete a hexameric ring but discarding those solutions producing steric clashes with contiguous monomers.
