Remark 300 | BIOMOLECULE: 1 THIS ENTRY CONTAINS THE CRYSTALLOGRAPHIC ASYMMETRIC UNIT WHICH CONSISTS OF 1 ... BIOMOLECULE: 1 THIS ENTRY CONTAINS THE CRYSTALLOGRAPHIC ASYMMETRIC UNIT WHICH CONSISTS OF 1 CHAIN(S). The biological unit is a dimer. However, the biological dimer is not contained in the crystal. The dimer model cannot be generated by a simple coordinate transformation of the crystal structure. The biological dimer can, however, be modelled based on the surface properties of the crystal structure, and on solution small-angle X-ray scattering data. |
