Figure 5

Charged amino acids in the extracellular domains of CXCR4 and CCR5. The diagramm shows a schematic representation of the extracellular domains of CXCR4 and CCR5. Indicated are positively and negatively charged amino acids and the glycans attached to asparagine residues. Symbol plus, lysine (K) and arginine (R) amino acid residues; symbol minus, glutamic (E) and aspartic (D) acid amino acid residues.
