Wide-line šH NMR is an efficient spectroscopic method to determine the disorder tendency of a protein. It directly measures the properties of the hydration shell of proteins, delivering exact and measurable values of their disorder/order content. A comparison is performed between several globular and disordered proteins. The common properties of the subzero mobile hydration water of these two groups were investigated. The amount of the mobile hydration water and the shape of the melting diagram...

Wide-Line NMR Melting Diagrams, Their Thermodynamic Interpretation, and Secondary Structure Predictions for A30P and E46K ?-Synuclein
Parkinson's disease is thought to be caused by aggregation of the intrinsically disordered protein, ?-synuclein. Two amyloidogenic variants, A30P, and E46K familial mutants were investigated by wide-line šH NMR spectrometry as a completion of our earlier work on wild-type and A53T ?-synuclein (Bokor M. et al. WT and A53T ?-synuclein systems: melting diagram and its new interpretation. Int. J. Mol. Sci.2020, 21, 3997.). A monolayer of mobile water molecules...

[NMR paper] Protein-Protein Connections-Oligomer, Amyloid and Protein Complex-By Wide Line (1)H NMR
Protein-Protein Connections-Oligomer, Amyloid and Protein Complex-By Wide Line (1)H NMR
The amount of bonds between constituting parts of a protein aggregate were determined in wild type (WT) and A53T ?-synuclein (?S) oligomers, amyloids and in the complex of thymosin-?(4)-cytoplasmic domain of stabilin-2 (T?(4)-stabilin CTD). A53T ?S aggregates have more extensive ?sheet contents reflected by constant regions at low potential barriers in difference (to monomers) melting diagrams (MDs). Energies of the intermolecular interactions and of secondary structures bonds, formed during...

The PROSECCO server for chemical shift predictions in ordered and disordered proteins
The PROSECCO server for chemical shift predictions in ordered and disordered proteins
Abstract
The chemical shifts measured in solution-state and solid-state nuclear magnetic resonance (NMR) are powerful probes of the structure and dynamics of protein molecules. The exploitation of chemical shifts requires methods to correlate these data with the protein structures and sequences. We present here an approach to calculate accurate chemical shifts in both ordered and disordered proteins using exclusively the information contained in their sequences....
