From: Clustering of HIV-1 Subtypes Based on gp120 V3 Loop electrostatic properties
Charge distribution clustering analysis of the HIV-1 subtypes, from the year 2009 consensus sequences and structural template derived from the gp120 structure with PDB Code 2QAD. The horizontal axis of the dendrogram represents charge similarity distance. The net charge, global prevalence, coreceptor selectivity and geographies of each subtype are indicated in the figure for each subtype. N/A denotes that information was not available. Green circles in the branches of the dendrogram denote intersection points between net charges or infected population. The symbol * refers to the global prevalence of Subtype B which includes the two crystal structural templates (from 2QAD and 2B4C). The symbol # refers to the global prevalence of Subtype D which includes D and D35, combined.
