Figure 1From: Cloaked similarity between HIV-1 and SARS-CoV suggests an anti-SARS strategyWheel projection of the N-HR (a) and C-HR (b) of HIV-1 gp41 (gi|9629363). The amino acid sequence is displayed end-to-end down the axis of a schematic helix. The angle between every two consecutive amino acids is 102.9°. The helical wheel consists of seven corners, corresponding to the fit of seven amino acid residues into every two helical turns.Back to article page
