Figure 6

Comparison of charged amino acids between coreceptors and viral V3 loops. This comparison shows the number of charged amino acids in the extracellular domains of CXCR4 and CCR5 and the number in the V3 loop of the three viruses NL4-3, NL-952 and NL-991. Symbol plus (), lysine (K) and arginine (R) amino acid residues, Symbol minus (), glutamic (E) and aspartic (D) acid amino acid residues. Boxed, amino acids related to coreceptor usage
