Lanthanide labeling offers fast NMR approach to 3D structure determinations of protein-protein complexes

Pintacuda, Guido; Park, Ah Young; Keniry, Max; Dixon, Nicholas; Otting, Gottfried

Description

A novel nuclear magnetic resonance (NMR) strategy based on labeling with lanthanides achieves rapid determinations of accurate three-dimensional (3D) structures of protein-protein complexes. The method employs pseudocontact shifts (PCS) induced by a site-specifically bound lanthanide ion to anchor the coordinate system of the magnetic susceptibility tensor in the molecular frames of the two molecules. Simple superposition of the tensors detected in the two protein molecules brings them together...[Show more]
