Graphical Abstract
Graphical abstract Highlights
Introducing a paramagnetic metal ion into a protein allow the measurement of Residual Dipolar Couplings, Paramagnetic Relaxation Enhancements, and Pseudo-Contact Shifts. ? Introduction of a lanthanide ion into a protein leads to paramagnetic effects and partial alignment. ? Paramagnetic Relaxation Enhancements (PREs), Residual Dipolar Couplings (RDCs), and Pseudo-Contact Shifts (PCSs), among others, can be measured. ? Amplitude of paramagnetic effects depends on metal ions, protein size, and magnetic field strength. ? All paramagnetic effects and effects resulting from partial alignment are reviewed. ? Practical aspects include overview of tags used and characteristics of metal ions.

The double nucleus enhanced recoupling (DONER) experiment employs simultaneous irradiation of protons and deuterons to promote spin diffusion processes in a perdeuterated protein. This results in 4-5 times higher sensitivity in 2D 13C-13C correlation experiments as compared to PDSD. Here, a quantitative comparison of PDSD, 1H-DARR, 2H-DARR, and...
