Description

Paramagnetic relaxation enhancements (PRE) present a powerful source of structural information in nuclear magnetic resonance (NMR) studies of proteins and protein-ligand complexes. In contrast to conventional PRE reagents that are covalently attached to the protein, the complex between gadolinium and three dipicolinic acid (DPA) molecules, [Gd(DPA)3]3-, can bind to proteins in a non-covalent yet site-specific manner. This offers straightforward access to PREs that can be scaled by using...[Show more]
