Figure 2
(a, b) Cartoon representation of the SP009239–491 structure showing the swapped-domain dimer assembly in two orthogonal views. One protomer is coloured white and the other magenta (residues 39–366) and violet (residues 367–491). Each view is accompanied by a schematic representation of the swapped-domain dimer assembly. (c) Cartoon representation of a superposition of the SP009239–491 dimer structure (magenta, violet and white) with the monomeric structure of SP0092, called NgtS (green; PDB entry 5suo). The electron-density map of the hinge loop connecting the swapped and main domains (2mFo − DFc at 1σ) is shown in blue/white mesh. |
