Membrane Depth Measurements of E Protein by 2H ESEEM Spectroscopy in Lipid Bilayers [PDF]
BiophysicaA topological analysis was performed by taking ESEEM measurements of site-specifically labeled E protein from SARS-CoV-2. The intensity of deuterium modulation arising from either deuterated solvent or deuterated lipid acyl chains revealed exposure to ...

Structural dynamics of calmodulin-ryanodine receptor interactions: electron paramagnetic resonance using stereospecific spin labels [PDF]
Scientific Reports, 2018 We have used electron paramagnetic resonance, with rigid and stereospecific spin labels, to resolve structural states in calmodulin (CaM), as affected by binding of Ca and a CaM-binding peptide (RyRp) derived from the ryanodine receptor (RyR), the Ca ...

The integrable quantum group invariant A2n−1(2) and Dn+1(2) open spin chains
Nuclear Physics B, 2017 A family of A2n(2) integrable open spin chains with Uq(Cn) symmetry was recently identified in arXiv:1702.01482. We identify here in a similar way a family of A2n−1(2) integrable open spin chains with Uq(Dn) symmetry, and two families of Dn+1(2 ...

Strategies to identify and suppress crosstalk signals in double electron–electron resonance (DEER) experiments with gadoliniumIII and nitroxide spin-labeled compounds [PDF]
Magnetic Resonance, 2020 Double electron–electron resonance (DEER) spectroscopy applied to orthogonally spin-labeled biomolecular complexes simplifies the assignment of intra- and intermolecular distances, thereby increasing the information content per sample.

Site-specific structural order in Alzheimer's Aβ42 fibrils [PDF]
Royal Society Open Science, 2018 Deposition of amyloid fibrils is a pathological hallmark of Alzheimer's disease. Aβ42 is the major protein whose aggregation leads to the formation of these fibrils.

Spin-labeled polyribonucleotides [PDF]
Nucleic Acids Research, 1980 Poly (U), poly (C) and poly (A) were spin labeled with N-(2,2,5,5-tetramethyl-3-carbonylpyrroline-1-oxyl)-imidazole. This spin label interacts selectively with 2' OH ribose groups of polynucleotides and does not modify the nucleic acid bases. The extent of spin labeling is not dependent upon the nature of the base and is entirely determined by rigidity

RosettaEPR: rotamer library for spin label structure and dynamics. [PDF]
PLoS ONE, 2013 An increasingly used parameter in structural biology is the measurement of distances between spin labels bound to a protein. One limitation to these measurements is the unknown position of the spin label relative to the protein backbone. To overcome this
