Figure 4.
A. Molar mass distributions determined by sedimentation velocity, showing the PCSA-Monte Carlo distributions for HARS WT (black), HARS Y454S (red), and HARS R362H (blue). Molar masses are in excellent agreement with a dimer of each species. B. Frictional ratio anisotropies for HARS WT (black), HARS Y454S (red), and HARS R362H (blue) as a function of the sedimentation coefficient. Pseudo-3D plots derived from PCSA-Monte Carlo analyses of sedimentation velocity experiments. The right vertical axis indicates the partial concentration in terms of color density. All three samples show remarkable similarity.
