Figure 9.

Mapping of the residues requiring R_ex terms on the structure of SDF-1α dimer. The structure of dimeric SDF-1α is taken from Ohnishi et al. (2000) (PDB code 1QG7). The two monomers are shown in gray and blue, with the residues suspected to undergo chemical exchange indicated with labels on the blue monomer. Regions colored in red are directly involved in formation of dimer. Regions colored in pink may be indirectly affected by the formation of a dimer. Residues in black are missing from the model free analysis due to line broadening or inadequate quality of the extrapolations.
