Figure 3From: Observation of glycine zipper and unanticipated occurrence of ambidextrous helices in the crystal structure of a chiral undecapeptideNetwork of C-H...O hydrogen bonds at different interfaces. a) Stereo view for the network of Cα-H...O hydrogen bonds at Gly-Gly interface. The GXXG motif has promoted the close approach of opposite handed 310-helices there by encouraging the vander Waals and Cα-H...O interactions. b) Stereo view for the network of C-H...O hydrogen bonds at ΔPhe-ΔPhe interface.Back to article page
