a Insugen (I) chain C: secondary structure motifs (compare with Fig. 4a for chain A). b Insugen (I) Helix C1: GlyC1–SerC9. H-bonds are shown as green dashed lines. Main chain atoms only are shown. Compare with Figure S9b which shows the same region in porcine insulin [1]. c Insugen (I) chain C Helix C3: LeuC13–TyrC19. H-bonds are shown as green dashed lines. Main chain atoms only are shown.
