Structural analysis of CD4 and vWFC1. (Red) −RHStaple disulfide bonds both in CD4 and vWFC1; (black) other types of disulfide bonds. (A) Structures of CD4 and vWFC1 with disulfide bonds. Cys130-Cys159 in CD4 and Cys27-Cys37 in vWFC1 are linking antiparallel β-strands. (B) Dihedral angles (compare Fig. 1A) for selected disulfide bonds, with −RHStaple (red) and other disulfides (black). Dihedral angles for the three remaining disulfides in vWFC1 are given in Fig. S5. (C) Disulfide bond length. (D) C-S-S angles. Two neighboring bars stand for two adjacent angles of each disulfide bond. In panels C and D, bars on the left are for CD4, on the right for vWFC1. (Blue horizontal lines) Equilibrium parameters in the OPLS/AA force field.
