Specific isotopic labeling of methyl groups in a perdeuterated protein background enables the detection of long range NOEs in proteins or high molecular weight complexes. We introduce here an approach, combining an optimized isotopic labeli...
Simultaneous recording of intra- and inter-residue linking experiments for backbone assignments in proteins at MAS frequencies higher than 60 kHz [0.03%]

Nuclear magnetic resonance (NMR) has the unique advantage of elucidating the structure and dynamics of biomolecules in solution at physiological temperatures, where they are in constant movement on timescales from picoseconds to millisecond...
Non-uniform sampling in quantitative assessment of heterogeneous solid-state NMR line shapes [0.03%]

Non-uniform sampling has been successfully used for solution and solid-state NMR of homogeneous samples. In the solid state, protein samples are often dominated by inhomogeneous contributions to the homogeneous line widths. In spite of diff...
2-Fluorotyrosine is a valuable but understudied amino acid for protein-observed 19F NMR [0.03%]
氟代氨基酸2-氟酪氨酸在蛋白质观测型~(19)F NMR中的应用及前景

Peter D Ycas et al.
Incorporation of 19F into proteins allows for the study of their molecular interactions via NMR. The study of 19F labeled aromatic amino acids has largely focused on 4-,5-, or 6-fluorotryptophan, 4-fluorophenylalanine, (4,5, or 6FW) or 3-fl...
Backbone and methyl assignment of bacteriorhodopsin incorporated into nanodiscs [0.03%]

Here we present the XIPP (eXtensible Interactive Peak Picker) NMR software for analyzing multidimensional NMR data of proteins, DNA, RNA and protein-nucleic acid complexes. XIPP organizes experiments into pre-defined studies and replaces ou...
Intra-residue methyl-methyl correlations for valine and leucine residues in large proteins from a 3D-HMBC-HMQC experiment [0.03%]
