Fig. 7From: Ultra-high resolution X-ray structures of two forms of human recombinant insulin at 100 K a Insugen (I) chain D: secondary structure motifs. b Insugen (I) chain D helix D2. H-bonds are shown as green dashed white lines. Main chain atoms only are shown. c Insugen (I) chain D: type I turn. Main chain atoms only are shown. The H-bond is shown as a green dashed line. There is no corresponding secondary structure element in chain B, Fig. 6a. Drawn with Biovia, Discovery Studio 2016 [35]Back to article page
