Symmetry detection using ProSHADE. The map corresponding to a bacteriophage T4 portal protein (PDB entry 3ja7, EMDB entry EMD-6324; Sun et al., 2015) visualized using UCSF Chimera (Pettersen et al., 2004). ProSHADE reports the correct C12 symmetry, with the symmetry axis along the vector (0.02, 0.02, 1.00) with an average cross-correlation between the original structure and the structures rotated along this symmetry axis of 0.443. All symmetry elements present for this instance of the C12 symmetry group are reported, along with the list of alternative symmetries that are also present in the structure (C6, C4, C3 and C2) and the corresponding rotation-function peak heights. |
