Type of curve: sec
Comments: 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. In the order of deposition: Model number; Stoichiometry; MW (kDa); source; Volume fraction. 1; 1; 21; Crystal Structure; 0.382. 2; 1; 21; EOM; 0.106. 3; 1; 21; EOM; 0.397. 4; 2; 42; clustering Spacegroup; 0.081. 5; 4; 84; clustering Spacegroup; 0.034.
