Details | Molecule is homodimer in solution. The biological unit is a dimer. Three dimers form a crystallographic hexamer which is non-biological. The asymmetric unit contains half of a hexamer, chains ABC. Chains B,C were not treated as independent during refinement but were generated by strict non-crystallographic symmetry. |
