Figure 1: Location of the mutations on the structure of the influenza fusion peptide.

The structure of the WT peptide in detergent micelles [13] is displayed in the left panel. The other panels show the location of the mutations analysed in this work, which are highlighted in green. The peptide backbone is shown with a grey cartoon representation and the residue side chains are displayed as sticks with carbon, oxygen, nitrogen and hydrogen atoms coloured in grey, red, blue and white, respectively.
