FIGURE 4.
Results of the methyl-TCS experiments performed in the presence of AMD3100. A, ΔRR was calculated for each resonance, as in Fig. 3B. Red, light red, orange, and cyan bars represent the signals with ΔRR > 0.125, 0.100, 0.075, and <0.075, respectively. Methyl protons completely buried in the structures are shaded in gray. B, mapping of the affected residues on the SDF-1α structure (Protein Data Bank code 1VMC), as in Fig. 3C. Colors are the same as in A.
