Secondary structure predictions from NMR chemical shift assignments. The TALOS-N webserver (https://spin.niddk.nih.gov/bax/nmrserver/talosn) was used to predict the secondary structures of free ProXp-ala (A) and ProXp-ala bound to microhelixPro (B) using assigned HN, N, Cα, and Cβ chemical shifts. The red bars indicate probability for the α-helix, and the blue bars indicate probability for the β-strand. Unassigned residues are depicted as gray bars. The secondary structure of the ProXp-ala crystal structure (PDB ID code 1VJF) is displayed above each plot for comparison.
