Figure 3: Significant changes in subtype A sequences.
From: Genotypic Prediction of Co-receptor Tropism of HIV-1 Subtypes A and C

Consensus sequences of V2, V3 and V4 are shown for subtype A. Significant changes of amino acid compositions that have been detected with SeqFeatR are highlighted in grey and marked with asterisks. The loops are shown in bold. The regions around V3 and V2 show strongest statistical differences in amino acid composition.
