RCI - Random Coil Index for predicting protein flexibility from chemical shifts
RCI website
RCI method predicts protein flexibility by calculating the Random Coil Index from backbone chemical shifts and predicting values of model-free order parameters as well as per-residue RMSF of NMR and MD ensembles from the Random Coil Index.
The key advantages of this protocol over existing methods of studying protein flexibility are (i) it does not require prior knowledge of a protein's tertiary structure, (ii) it is not sensitive to the protein's overall tumbling and (iii) it does not require additional NMR measurements beyond the standard experiments for backbone...

The secondary structure and topology of membrane proteins can be described by inspection of two-dimensional (1)H-(15)N dipolar coupling/(15)N chemical shift polarization inversion spin exchange at the magic angle spectra obtained from uniformly (15)N-labeled samples in oriented bilayers. The characteristic...

Abstract:
Protein flexibility lies at the heart of many protein–ligand binding events and enzymatic activities. However, the experimental measurement of protein motions is often difficult, tedious and error-prone. As a result, there is a considerable interest in developing simpler and faster ways of quantifying protein flexibility. Recently, we described a method, called Random Coil Index (RCI), which appears to be able to...
