Beta turn type II'

[Beta turn type II']

Fragments are given by their PDB code, (chain number,) and the PDB residue number of the first position in the fragment.
The PDB style files of the fragments contain the neighbouring two residues for each terminal.
Backbone structures are obtained using ProteinViewer, where N-terminal is colored red and C-terminal blue.
