a Insugen (I) chain A, secondary structure motifs. b Insugen (I) Helix A1: GlyA1–SerA9. With the exception of side-chains GlyA1 and IleA2 which are shown completely, only main chain atoms are shown. H-bonds are shown as green dotted lines. Compare with Figure S9a which shows the same region in porcine insulin [1]. c Insugen (I) Helix A3: LeuA13–TyrA19. H-bonds are shown as green dotted lines. Main chain atoms only are shown. Drawn with Biovia, Discovery Studio 2016 [35]
