An NMR method to study protein-protein interactions.
Methods Mol Biol. 2012;757:129-37
Authors: Nishida N, Shimada I
Abstract
Specific interactions between proteins are a fundamental process underlying the various biological events, such as cell-cell contacts, signal transduction, and gene expression. Therefore, the structural investigations of protein-protein interactions provide useful information for understanding these events. We describe an NMR method, termed the cross-saturation (CS) method, to determine the binding sites of protein complexes more precisely than conventional NMR methods. The CS method can determine the binding sites of a protein complex that undergoes fast exchange between the free and the bound states, regardless of the molecular size of the complex.

Nonradioactive 31P-NMR spectroscopy has previously been used for the study of protein phosphorylations. However, the procedures does not seem to be easy for non-experts of this field, hence, this approach has not been widely used. We introduce here a simple protocol with...

Efficient protein production method for NMR using soluble protein tags with cold shock expression vector
Abstract The E. coli protein expression system is one of the most useful methods employed for NMR sample preparation. However, the production of some recombinant proteins in E. coli is often hampered by difficulties such as low expression level and low solubility. To address these problems, a modified cold-shock expression system containing a glutathione S-transferase (GST) tag, the pCold-GST system, was investigated. The pCold-GST system successfully expressed 9 out of 10 proteins...
