Because proteins are well-characterized and this work takes inspiration from protein design, we compiled a set of 304 PDB files of single protein species. These PDB files were used as an input to obtain simulated SAXS I(q) vs q. The simulated data was generated in CRYSOL, a program in the ATSAS software suite. For a q range of 0-0.25 Å -1 , default parameters were used except for the number of points in the q range which was increased to 200 points. With the simulated SAXS data, the same analysis was completed as was done for experimental data of copolymers and copolymer conjugates to compute Rg, Dmax, Porod exponent, and Porod volume. These structure files were also input into HullRad which can calculate hydrodynamic size with a convex hull model. The FASTA files associated with each PDB entry selected were then used to calculate chemical parameters such as molecular weight, total charge, total positive charge, total negative charge, log P, and HLB.
