Generation of pseudocontact shifts in protein NMR spectra with a genetically encoded cobalt(II)-binding amino acid

Nguyen, Thi Kelly; Ozawa, Kiyoshi; Stanton-Cook, Mitchell; Barrow, Russell; Huber, Thomas; Otting, Gottfried

Description

Playing tag: Incorporation of the genetically encoded amino acid bipyridylalanine into a protein creates a site-specific binding site for CoII. Pronounced pseudocontact shifts generated by the CoII ion in the NMR spectra delivers powerful long-range structure information for the facile analysis of proteins as well as protein-protein and protein-ligand complexes (see picture for a representation of the psuedocontact shift in the protein).
