Abstract
NMR structure determination of soluble proteins depends in large part on distance restraints derived from NOE. In this study, we examined the impact of paramagnetic relaxation enhancement (PRE)-derived distance restraints on protein structure determination. A high-resolution structure of the loop-rich soluble protein Sin1 could not be determined by conventional NOE-based procedures due to an insufficient number of NOE restraints. By using the 867 PRE-derived distance restraints obtained from the NOE-based structure determination procedure, a high-resolution structure of Sin1 could be successfully determined. The convergence and accuracy of the determined structure were improved by increasing the number of PRE-derived distance restraints. This study demonstrates that PRE-derived distance restraints are useful in the determination of a high-resolution structure of a soluble protein when the number of NOE constraints is insufficient.

Paramagnetic NMR spectroscopy has evolved rapidly in the last decade, and has shown to be a very useful tool for solving structures of protein–protein complexes. A major breakthrough has been the development of paramagnetic metal binding tags that can be attached specifically to the protein. These tags have greatly...

Tunable paramagnetic relaxation enhancements by [Gd(DPA)3]3â?? for protein structure
Abstract Paramagnetic relaxation enhancements (PRE) present a powerful source of structural information in nuclear magnetic resonance (NMR) studies of proteins and proteinâ??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, 3â??, can bind to proteins in a non-covalent yet site-specific manner. This offers straightforward access to PREs that can be scaled by using different ratios of 3â?? to protein, allowing quantitative distance measurements for nuclear spins...
