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...

Structural details of amyloid beta oligomers in complex with human prion protein as revealed by solid-state MAS NMR spectroscopy
Human PrP (huPrP) is a high-affinity receptor for oligomeric amyloid-? (A?) protein aggregates. Binding of A? oligomers to membrane-anchored huPrP has been suggested to trigger neurotoxic cell signaling in Alzheimer's disease, while an N-terminal soluble fragment of huPrP can sequester A? oligomers and reduce their toxicity. Synthetic oligomeric A? species are known to be heterogeneous, dynamic and transient, rendering their structural investigation particularly...

The â??long tailâ?? of the protein tumbling correlation function: observation by 1 H NMR relaxometry in a wide frequency and concentration range
Abstract
Inter-protein interactions in solution affect the auto-correlation function of Brownian tumbling not only in terms of a simple increase of the correlation time, they also lead to the appearance of a weak slow component (â??long tailâ??) of the correlation function due to a slowly changing local anisotropy of the microenvironment. The conventional protocol of correlation time estimation from the...

[Question from NMRWiki Q&A forum] How to extract residue information in case of line broadening (intensity drop ) of HSQC titration of protein - protein interaction data ?
How to extract residue information in case of line broadening (intensity drop ) of HSQC titration of protein - protein interaction data ?
Dear Friends
we have done HSQC gradient titration with targeted proteins , most of cross peaks we observed intensity drop , 30 out of 95 peaks ( 70 percent intensity drop of each cross peak ) , other cross peaks also we observe intensity drop less than 70 percent , we did n"t observe any chemical shift change .( May be it is due to intermediate exchange regime of complex ) .ITC experiment showing 12uM binding constant .AUC experiment result is...
