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

, 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 ...

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 ...

High FOXA1 levels induce ER transcriptional reprogramming, a pro-metastatic secretome, and metastasis in endocrine-resistant breast cancer

Cell Reports, 2023
Summary: Aberrant activation of the forkhead protein FOXA1 is observed in advanced hormone-related cancers. However, the key mediators of high FOXA1 signaling remain elusive.

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.

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 ...
