17 O Hyperfine Spectroscopy Reveals Hydration Structure of Nitroxide Radicals in Aqueous Solutions
Autor: Fabian Hecker, Lisa Fries, Markus Hiller, Mario Chiesa, Marina Bennati
Publikováno v: Angewandte Chemie, International Edition in English
The hydration structure of nitroxide radicals in aqueous solutions is elucidated by advanced 17O hyperfine (hf) spectroscopy with support of quantum chemical calculations and MD simulations. A piperidine and a pyrrolidine-based nitroxide radical are

The Journal of the American Chemical Society
The role of water in biological proton-coupled electron transfer (PCET) is emerging as a key for understanding mechanistic details at atomic resolution. Here we demonstrate 17O high-frequency electron–nuclear double resonance (ENDOR) in conjunction

Trapping x‐ray radiation damage from homolytic Se–C bond cleavage in BnSeSeBn crystals (Bn=benzyl, CH2C6H5)
Autor: Christian J. Schürmann, Thorsten L. Teuteberg, A. Claudia Stückl, Paul Niklas Ruth, Fabian Hecker, Regine Herbst‐Irmer, Ricardo A. Mata, Dietmar Stalke
Publikováno v: Angewandte Chemie International Edition
Irradiation of dibenzyl diselenide BnSeSeBn with X-ray or UV-light cleaves the Se-C and the Se-Se bonds, inducing stable and metastable radical states. They are inevitably important to all natural and life sciences. Structural changes due to X-ray-in

19F Electron-nuclear double resonance reveals interaction between redox-active tyrosines across the α/β interface of E. coli ribonucleotide reductase
Autor: Andreas Meyer, Annemarie Kehl, Chang Cui, Fehmke A. K. Reichardt, Fabian Hecker, Lisa-Marie Funk, Manas K. Ghosh, Kuan-Ting Pan, Henning Urlaub, Kai Tittmann, JoAnne Stubbe, Marina Bennati
Publikováno v: Journal of the American Chemical Society
Ribonucleotide reductases (RNRs) catalyze the reduction of ribonucleotides to deoxyribonucleotides, thereby playing a key role in DNA replication and repair. Escherichia coli class Ia RNR is an α2β2 enzyme complex that uses a reversible multistep r

1H high field electron-nuclear double resonance spectroscopy at 263 GHz/9.4 T
Autor: Müge Kasanmascheff, Igor Tkach, Fabian Hecker, Markus Hiller, Peter Höfer, Marina Bennati, Isabel Bejenke, Ion Prisecaru, Igor Gromov, Annemarie Kehl
Publikováno v: Journal of Magnetic Resonance
We present and discuss the performance of 1H electron-nuclear double resonance (ENDOR) at 263 GHz/9.4 T by employing a prototype, commercial quasi optical spectrometer. Basic instrumental features of the setup are described alongside a comprehensive

A systematic review and analysis of the most stable spatial arrangements of n carbon, n oxygen, and 2n hydrogen atoms including vibrational zero-point energy up to n = 5 shows that small-molecule aggregates win, typically followed by thermally unstab
