Figure 3

(a) Detail from the crystal structure of 2 showing participation of the triazole residue in main chain hydrogen bonding; residues and nitrogen atoms of the triazole ring are numbered. (b) A top down view of the crystal structure of 3 showing the hydrophobic plate formed by the triazole ε2 residues and inter-chain hydrogen bonds bridged by water. (c) Detail of two chains from the crystal structure of 3 showing the inter-helical crossing. Dashed lines indicate hydrogen bonds. In (a) and (c), H atoms are modeled based on N, C, and O coordinates.10
