Figure 1

(a,b) The molecular structures of c(Pro-Phe-Pro-Phe) (sample A) and c(Pro-Phe-Pro-D-Phe) (sample B) crystals showing the atom-labeling scheme. The displacement ellipsoids are drawn with 50% probability level and the H atoms are shown as small spheres of arbitrary radius. (c) The superposition of the analyzed cyclic peptide molecules; c(Pro-Phe-Pro-Phe) and c(Pro-Phe-Pro-D-Phe) are shown as yellow and cyan, respectively.
