Figure 7From: 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 tropismPredicted glycosylation profile of the V3 loop sequences. The X-axis shows the positions along the V3 loop (numbering of the whole-length gp120); the Y-axis, the relative frequency of occurrence of a potential glycosylation site (predicted with N-GlycoSite [23]) in the dataset from [25].Back to article page
