Figure 2:

(a) Radius of gyration $R_{\mathrm{g}}$ as a function of nSCD for the EKVs in Figure 1 along with representative conformations for select EKVs. The inset shows the relative anisotropy $⟨{\kappa }^2⟩$ as a function of nSCD for the same EKVs. (b) End-to-end distance $R_{\mathrm{e}}$ as a function of nSCD for the same EKVs. The inset shows the correlation between $R_{\mathrm{g}}$ and $R_{\mathrm{e}}$ from the simulations compared to the theoretical expectation for an ideal chain $R_{\mathrm{g}}=R_{\mathrm{e}}/\sqrt{6}$. (c) Interresidue distance $R_{ij}$ as a function of residue separation in the chain $|i-j|$ for select EKVs. The dashed line corresponds to the ideal chain scaling $R_{ij}=b|i-j{|}^{1/2}$, where $b=6.39\mathrm{\AA }$ was fitted for EKV1 using the theoretically expected end-to-end distance $R_{\mathrm{e}}^2=N{b}^2$ of an ideal chain with $N=50$. The symbol color, ranging from purple to red, indicates increasing nSCD. The same color scale is used in the inset of (b).
