Figure 1From: Observation of glycine zipper and unanticipated occurrence of ambidextrous helices in the crystal structure of a chiral undecapeptideStereo view for the molecular conformation of the undeacapeptide. A denotes a left-handed 310-helix and B aright-handed 310 helix. The helices A and B are antiparallel to each other.Back to article page
