Bayesian optimization to estimate hyperfine couplings from 19F ENDOR spectra [PDF]

, 2023
ENDOR spectroscopy is a fundamental method to detect nuclear spins in the vicinity of paramagnetic centers and their mutual hyperfine interaction. Recently, site-selective introduction of 19F as nuclear labels has been proposed as a tool for ENDOR-based ...

Distribution of H$^\beta$ Hyperfine Couplings in a Tyrosyl Radical Revealed by 263 GHz ENDOR Spectroscopy

, 2023
1 H ENDOR spectra of tyrosyl radicals (Y∙ ) have been the subject of numerous EPR spectroscopic studies due to their importance in biology. Nevertheless, assignment of all internal 1 H hyperfine couplings has been challenging because of substantial ...

Reverse dynamic nuclear polarisation for indirect detection of nuclear spins close to unpaired electrons [PDF]

Magnetic Resonance, 2022
Polarisation transfer schemes and indirect detection are central to magnetic resonance. Using the trityl radical OX063 and a pulse electron paramagnetic resonance spectrometer operating in the Q-band (35 GHz, 1.2 T), we show here that it is possible to ...

A Proton ENDOR Study of Azurin [PDF]

Applied Magnetic Resonance, 2009
As part of our ongoing project that aims at the optimum characterization of the electronic structure of the blue-copper site of azurin from Pseudomonas aeruginosa, we present the complete hyperfine tensors of the protons bound to the Cbeta atom of the copper-bound cysteine 112.

Resolution of chemical shift anisotropy in 19F ENDOR spectroscopy at 263 GHz/9.4 T

, 2021
Pulsed 19F ENDOR spectroscopy provides a selective method for measuring angstrom to nanometer distances in structural biology. Here, the performance of 19F ENDOR at fields of 3.4 T and 9.4 T is compared using model compounds containing one to three 19F ...

Involvement of miR-190b in Xbp1 mRNA Splicing upon Tocotrienol Treatment

Molecules, 2020
We previously demonstrated that apoptosis induced by tocotrienols (γ and δT3) in HeLa cells is preceded by Ca2+ release from the endoplasmic reticulum. This event is eventually followed by the induction of specific calcium-dependent signals, leading to ...
