Katsikis, S., et al., Improved Stability and Spectral Quality in Ex Situ Dissolution DNP Using an Improved Transfer Device. Appl. Magn. Reson., 2015: p. 1-7.
Dissolution dynamic nuclear polarization (DNP) has become one of the predominant implementations for DNP. However, the technical implementation of transferring the sample from the polarizer to the nuclear magnetic resonance (NMR) system remains challenging. There is a need for additional technical optimizations in order to use dissolution DNP for biochemical and chemical applications. Here we show how a newly designed pressure dissolution kit considerably improves spectral quality and stability by enabling highly reliable and fast sample transfer to the NMR system.

Improved reliability, accuracy and quality in automated NMR structure calculation with ARIA
Abstract
In biological NMR, assignment of NOE cross-peaks and calculation of atomic conformations are critical steps in the determination of reliable high-resolution structures. ARIA is an automated approach that performs NOE assignment and structure calculation in a concomitant manner in an iterative procedure. The log-harmonic shape for distance restraint potential and the Bayesian weighting of distance restraints, recently introduced in ARIA, were shown to...

HNCA+, HNCO+, and HNCACB+ experiments: improved performance by simultaneous detection of orthogonal coherence transfer pathways
HNCA+, HNCO+, and HNCACB+ experiments: improved performance by simultaneous detection of orthogonal coherence transfer pathways
Abstract
Three experiments, BESTâ??TROSY HNCA+, HNCO+ and HNCACB+ are presented for sequential backbone resonance assignment of 13C, 15N labelled proteins. The novelty of these experiments with respect to conventional pulse sequences is the detection of additional orthogonal coherence transfer pathways that results in enhanced sensitivity for sequential correlations without significantly compromising the intensity of...
An improved algorithm for MFR fragment assembly
An improved algorithm for MFR fragment assembly
Abstract A method for generating protein backbone models from backbone only NMR data is presented, which is based on molecular fragment replacement (MFR). In a first step, the PDB database is mined for homologous peptide fragments using experimental backbone-only data i.e. backbone chemical shifts (CS) and residual dipolar couplings (RDC). Second, this fragment library is refined against the experimental restraints. Finally, the fragments are assembled into a protein backbone fold using a rigid body docking algorithm using the RDCs as...
