[NMR paper] Rapid Characterization of Structural and Behavioral Changes of Therapeutic Proteins by Relaxation and Diffusion (1)H-SOFAST NMR Experiments
Biologic drugs have emerged as a rapidly expanding and important modality, offering promising therapeutic solutions by interacting with previously "undruggable" targets, thus significantly expanding the range of modern pharmaceutical applications. However, the inherent complexity of these drugs also introduces liabilities and poses challenges in their development, necessitating efficient screening methods to evaluate the structural stability and behavior. Although nuclear magnetic resonance...
Simultaneous measurement of 1 H C/N -R 2 â?²s for rapid acquisition of backbone and sidechain paramagnetic relaxation enhancements (PREs) in proteins
Simultaneous measurement of 1 H C/N -R 2 â?²s for rapid acquisition of backbone and sidechain paramagnetic relaxation enhancements (PREs) in proteins
Abstract
Paramagnetic relaxation enhancements (PREs) are routinely used to provide long-range distance restraints for the determination of protein structures, to resolve protein dynamics, ligandâ??protein binding sites, and lowly populated species, using Nuclear Magnetic Resonance Spectroscopy (NMR). Here, we propose a simultaneous 1H-15Â*N, 1H-13C SESAME based pulse scheme for the rapid acquisition of...

BEST and SOFAST experiments for resonance assignment of histidine and tyrosine side chains in 13 C/ 15 N labeled proteins
BEST and SOFAST experiments for resonance assignment of histidine and tyrosine side chains in 13 C/ 15 N labeled proteins
Abstract
Aromatic amino-acid side chains are essential components for the structure and function of proteins. We present herein a set of NMR experiments for time-efficient resonance assignment of histidine and tyrosine side chains in uniformly 13C/15N-labeled proteins. The use of band-selective 13C pulses allows to deal with linear chains of coupled spins, thus avoiding signal loss that occurs in branched spin systems during...
Measuring hydrogen exchange in proteins by selective water saturation in 1Hâ??15N SOFAST/BEST-type experiments: advantages and limitations
Measuring hydrogen exchange in proteins by selective water saturation in 1Hâ??15N SOFAST/BEST-type experiments: advantages and limitations
Abstract
HETex-SOFAST NMR (Schanda et al. in J Biomol NMR 33:199â??211, 2006) has been proposed some years ago as a fast and sensitive method for semi-quantitative measurement of site-specific amide-water hydrogen exchange effects along the backbone of proteins. Here we extend this concept to BEST readout sequences that provide a better resolution at the expense of some loss in sensitivity. We discuss the...
