Electrostatic potential maps show complementarity between a single molecule of SDF-1 (chain A) and both CXCR4 N-termini (chains B and D). Sulfation sites on the CXCR4 N-termini, and SDF-1 residues which hydrogen bond to these sites, are shown as sticks. Figures are displayed at isovalue surfaces of ±1 kTe. [Color figure can be viewed in the online issue, which is available at http://wileyonlinelibrary.com.]
