Figure 4From: Modelling binding between CCR5 and CXCR4 receptors and their ligands suggests the surface electrostatic potential of the co-receptor to be a key player in the HIV-1 tropismSurface electrostatic potential of the coreceptors. Electrostatic potential for structures of CCR5 (modelled) and CXCR4 (modified from PDB entry 3oe0) calculated with ABPS [36]. Red corresponds to a potential of -5 kT/e; blue, 5 kT/e.Back to article page
