"description": "Scattering data are fitted using the ATSAS OLIGOMER program using a suite of models. The ATSAS program FFMAKER was used to generate form factors for each model in the suite. Each model is assigned a volume fraction to fit the observed scattering profile. 3 monomer models are included, the first is a compact conformation of PDZ1-2 similar to PDB entries 6spv/6spz; the other two are domain models obtained from a representative run of the ATSAS EOM program with data projected to infinite dilution. Multimeric models are drawn from a \"clustering Spacegroup\", unit cell 14.8nm symmetry I2(1)3, and consist of identical copies of an extended conformation of PDZ1-2 (similar to PDB entry 3zrt) assembled by symmetry operations. \r\n\r\nIn the order of deposition: \r\nModel number; Stoichiometry; MW (kDa); source; Volume fraction. \r\n 1; 1; 21; Crystal Structure; 0.112.\r\n 2; 1; 21; EOM; 0.186.\r\n 3; 1; 21; EOM; 0.656.\r\n 4; 2; 42; clustering Spacegroup; 0.000.\r\n 5; 4; 84; clustering Spacegroup; 0.000.\r\n 6; 8; 168; clustering Spacegroup; 0.034.\r\n 7; 12, 252; clustering Spacegroup; 0.005.\r\n 8; 16, 336, clustering Spacegroup; 0.000.\r\n 9; 20, 420, clustering Spacegroup; 0.000.\r\n 10; 24, 504, clustering Spacegroup; 0.006.",

One solute concentration of 15.00 mg/ml was measured at 15°C. 15 successive 0.050 second frames were collected. The data were normalized to the intensity of the transmitted beam and radially averaged; the scattering of the solvent-blank was subtracted.",
