Figure 2
The conformation of Boc-Tyr-D-Ala-Gly-NMe-Phe-Met-OMe. The two independent peptide molecules are superimposed (alignment was based on the positions of the main-chain N and O atoms). Although the two independent molecules have similar conformations, even the main-chain atoms cannot be superimposed. Additional differences are present in the orientations of the side chains. |
