The combination of chemical shift, residual dipolar coupling, and backbone relaxation data can be used to characterize the nature of a domain interface in a multidomain protein. Comparison of the parameters obtained from isolated domains and domain pairs provides insight into the composition of the interface as well as into interdomain dynamics. The interface between the 13th and 14th F3 module from fibronectin is used as an example.

Structural determination of biomolecular interfaces by nuclear magnetic resonance of
Abstract Protein interactions are important for understanding many molecular mechanisms underlying cellular processes. So far, interfaces between interacting proteins have been characterized by NMR spectroscopy mostly by using chemical shift perturbations and cross-saturation via intermolecular cross-relaxation. Although powerful, these techniques cannot provide unambiguous estimates of intermolecular distances between interacting proteins. Here, we present an alternative approach, called REDSPRINT (REDduced/Standard PRoton density INTerface identification), to map protein interfaces with...
