Sometimes I displayed the cartoon view of a protein in PyMOL as the figures shown below that I don’t really see the helix and strands. It often happens when I merged 10 or 20 structures into a NMR ensemble file. All 20 structures are aligned but the secondary structural regions are not clearly displayed [...]

For an amino acid in protein, its chemical shift, delta(phi, psi)(s), is expressed as a function of its backbone torsion angles (phi and psi) and secondary state (s): delta(phi, psi)(s=deltaphi, psi)_coil+Deltadelta(phi, psi)_s), where delta(phi, psi)(coil) represents its chemical shift at coil state (s=coil); Delta delta(phi, psi)(s) (s=sheet or helix) is...

[Question from NMRWiki Q&A forum] NMR experiments to assign aromatic sidechains?
NMR experiments to assign aromatic sidechains?
Hello, may I ask this - NMR experiments/pulse sequences are available to assign aromatic sidechains - Phe, Tyr, Trp? We'd like to try 2D and 3D.
What's available in the vendor-specific libraries?
Thank you very much.

Science. 1993 Jun 4;260(5113):1491-6
Authors: de Dios AC, Pearson JG, Oldfield E
Recent theoretical developments permit the prediction of 1H, 13C, 15N, and 19F nuclear magnetic resonance chemical shifts in proteins and offer new ways of analyzing secondary and tertiary structure as well as for probing protein electrostatics. For 13C,...
