Out of the best 20 calculated structures. The distance is the mean distance between two alpha carbons ± standard deviation (SD). The sequences with less than 7 Å distance between alpha carbons of i th and (i + 3) rd residues without helical structure were considered as a β-turn.41 Bzl stands for the benzyl moiety at the C-terminus.
