Quaternary structure of APEG-1 and ΔAPEG-1. A: Ribbon diagram of the ΔAPEG-1 homodimer. Bi-dentate salt bridges are represented by broken lines. Residues lined up at the binding interface are depicted. B: Analytical sedimentation equilibrium ultracentrifugation plot of determined molecular mass versus concentration of APEG-1 (white triangles) and ΔAPEG-1 (black spheres) at 100 mM NaCl. The mass of the respective homodimer is set to 100%. Inset: Dissociation constants of ΔAPEG-1 at different NaCl concentrations.
