NMR studies can provide unique information about protein conformations in solution. In CASP14, three reference structures provided by solution NMR methods were available (T1027, T1029, and T1055), as well as a fourth data set of NMR-derived contacts for an integral membrane protein (T1088). For the three targets with NMR-based structures, the best prediction results ranged from very good (GDT_TS = 0.90, for T1055) to poor (GDT_TS = 0.47, for T1029). We explored the basis of these results by...

NMR hawk-eyed view of AlphaFold2 structures
The prediction of the three-dimensional structure of proteins from the amino acid sequence made a stunning breakthrough reaching atomic accuracy. Using the neural network-based method AlphaFold2 three-dimensional structures of almost the entire human proteome have been predicted and made available (https://www.alphafold.ebi.ac.uk). To gain insight into how well AlphaFold2 structures represent the conformation of proteins in solution, I here compare the AlphaFold2 structures of selected small...

Major groove width variations in RNA structures determined by NMR and impact of 13C r
Abstract Ribonucleic acid structure determination by NMR spectroscopy relies primarily on local structural restraints provided by 1Hâ?? 1H NOEs and J-couplings. When employed loosely, these restraints are broadly compatible with A- and B-like helical geometries and give rise to calculated structures that are highly sensitive to the force fields employed during refinement. A survey of recently reported NMR structures reveals significant variations in helical parameters, particularly the major groove width. Although helical parameters observed in high-resolution X-ray crystal structures of...
