Towards autonomous analysis of chemical exchange saturation transfer experiments using deep neural networks
Towards autonomous analysis of chemical exchange saturation transfer experiments using deep neural networks
Abstract
Macromolecules often exchange between functional states on timescales that can be accessed with NMR spectroscopy and many NMR tools have been developed to characterise the kinetics and thermodynamics of the exchange processes, as well as the structure of the conformers that are involved. However, analysis of the NMR data that report on exchanging macromolecules often hinges on complex least-squares fitting procedures as well as human...

Optimization of 1 H decoupling eliminates sideband artifacts in 3D TROSY-based triple resonance experiments
Optimization of 1 H decoupling eliminates sideband artifacts in 3D TROSY-based triple resonance experiments
Abstract
TROSY-based triple resonance experiments are essential for protein backbone assignment of large biomolecular systems by solution NMR spectroscopy. In a survey of the current Bruker pulse sequence library for TROSY-based experiments we found that several sequences were plagued by artifacts that affect spectral quality andÂ*hamper data analysis. Specifically, these experiments produce sidebands in the 13C(t 1)...

Speeding-up exchange-mediated saturation transfer experiments by Fourier transform
Speeding-up exchange-mediated saturation transfer experiments by Fourier transform
Abstract
Protein motions over various time scales are crucial for protein function. NMR relaxation dispersion experiments play a key role in explaining these motions. However, the study of slow conformational changes with lowly populated states remained elusive. The recently developed exchange-mediated saturation transfer experiments allow the detection and characterization of such motions, but require extensive measurement time. Here we show that, by making use of...

Comparison of the sensitivities of WaterLOGSY and saturation transfer difference NMR experiments
Abstract
The WaterLOGSY (WL) and saturation transfer difference (STD) NMR experiments have proven to be extremely useful techniques to characterize interactions between small molecules and large biomolecules. In this work we compare the relative sensitivities of WL and STD NMR using 3 experimental systems: ketoprofen (KET)â??bovine serum albumin (BSA), tert-butyl hydroquinone (TBHQ)â??hemagglutinin (HA), and chloramphenicol (CAM)â??ribosome (70S). In all...
