CheShift-2 is a web server designed for protein structure validation. CheShift-2 predicts the 13Cα chemical shifts from the atomic coordinates of a protein (pdb file). Alternative CheShift-2 is capable of a per-residue validation, the user must provide the atomic coordinates (pdf file) and the observed 13Cα chemical shifts.
Currently, there are four PyMOL plugins available:
Azahar extends the PyMOL's capabilities to visualize, analyze and model glycans and glycoconjugated molecules.
