Here we have used solution state NMR and circular dichroism spectroscopies to evaluate the extent of structural perturbations associated with five different Parkinson's disease linked DJ-1mutations: L166P, E64D, M26I, A104T, and D149A.
We investigated the active components against Parkinson's disease from <i>H. japonicus</i> fraction (HJF) using high performance liquid chromatography (HPLC) coupled with quadruple-time-of-flight mass spectroscopy (qTOF-MS) and NMR.
Here, we amplified α-synuclein aggregates from PD and MSA brain extracts and analyzed the conformational properties using fluorescent probes, NMR spectroscopy and electron paramagnetic resonance.
Based on NMR results, the plausible molecular mechanism of overlapping pathocascade of AD and PD in DLB due to interactions between alpha-Syn and Abeta is described.
The simplicity and effectiveness of the classification methodology proposed support the use of NMR spectroscopy, in combination with chemometrics, as a viable alternative diagnostic tool to conventional PD clinical diagnosis.
Our NMR data demonstrate conclusively that the differences observed in the conformational transitions triggered by Cu(I) binding to AcαS and AcβS find a correlation at the level of their backbone dynamic properties; added to the potential biological implications of these findings, this fact opens new avenues of investigations into the bioinorganic chemistry of PD.
