Figure 2. View of the backbone average structure of R16 (from His10 to Gln107). From the N to the C terminus, helix A is colored green, the AB loop red, helix B yellow, the BC turn red, and helix C cyan. Some of the side-chains of residues implicated in interhelical contacts are shown in white and labeled according to the one letter code for amino acid residues and in parenthesis according to the helices nomenclature.
