Abstract
Paramagnetic relaxation enhancements (PREs) are a rich source of structural information in protein solid-state NMR spectroscopy. Here we demonstrate that PRE measurements in natively diamagnetic proteins are facilitated by a thiol-reactive compact, cyclen-based, high-affinity Cu2+ binding tag, 1--1,4,7,10-tetraazacyclododecane (TETAC), that overcomes the key shortcomings associated with the use of larger, more flexible...

Abstract
An ensemble-based approach is presented to explore the conformational space sampled by a multi-domain protein showing moderate inter-domain dynamics in terms of translational and rotational motions. The strategy was applied on a complex of calmodulin (CaM) with the IQ-recognition motif from the voltage-gated calcium...

Phase cycling with a 240 GHz, free electron laser-powered electron paramagnetic resonance spectrometer
From the The DNP-NMR Blog:
Phase cycling with a 240 GHz, free electron laser-powered electron paramagnetic resonance spectrometer
This is not an article directly related to DNP spectroscopy. However, it shows the tremendous progress made in the development of high-frequency, high-power sources that can be utilized for high-field EPR and eventually DNP experiments.
