Journal ArticleDOI
High sensitivity and versatility of the DEER experiment on nitroxide radical pairs at Q-band frequencies
Yevhen Polyhach,Enrica Bordignon,René Tschaggelar,Sandhya Gandra,Adelheid Godt,Gunnar Jeschke +5 more
TL;DR: The performance improvement that can be achieved at Q-band frequencies (34.5 GHz) using a high-power spectrometer is quantified and it is demonstrated that a commercial Q- band spectrometers can be readily adjusted to the high- power operation.
Journal ArticleDOI
HYSCORE and DEER with an upgraded 95GHz pulse EPR spectrometer.
Daniella Goldfarb,Yaakov Lipkin,Alexey Potapov,Yehoshua Gorodetsky,Boris Epel,Arnold M. Raitsimring,Marina Radoul,Ilia Kaminker +7 more
TL;DR: The set-up of a new microwave bridge for a 95 GHz pulse EPR spectrometer is described, which opens a new window for the observation of relatively large hyperfine couplings, yet not resolved in the EPR spectrum, that are difficult to observe with HYSCORE carried out at conventional X-band frequencies.
Journal ArticleDOI
Pulsed dipolar spectroscopy distance measurements in biomacromolecules labeled with Gd(III) markers.
Ying Song,Thomas J. Meade,Andrei V. Astashkin,Eric L. Klein,John H. Enemark,Arnold M. Raitsimring +5 more
TL;DR: This work demonstrates the feasibility of using Gd(III) tags for long-range Double Electron Electron Resonance (DEER) distance measurements in biomacromolecules and indicates that distance measurements up to 100Å are possible.
Journal ArticleDOI
Distance measurements in model bis-Gd(III) complexes with flexible "bridge". Emulation of biological molecules having flexible structure with Gd(III) labels attached.
Alexey Potapov,Ying Song,Thomas J. Meade,Daniella Goldfarb,Andrei V. Astashkin,Arnold M. Raitsimring +5 more
TL;DR: This work explored Gd(III) as a possible spin label for high-field Double Electron-Electron Resonance (DEER) based distance measurements in biological molecules with flexible geometry and found the shortest limits of accessible distances to be as small as 13 A.
Journal ArticleDOI
Pulsed EPR Determination of the Distance between Heme Iron and FMN Centers in a Human Inducible Nitric Oxide Synthase
TL;DR: The relaxation-induced dipolar modulation enhancement (RIDME) technique is used to measure the electron spin echo envelope modulation caused by the dipole interactions between paramagnetic FMN and heme iron centers in the FMNH(*): FMN semiquinone form of a human inducible NOS (iNOS) bidomain oxygenase/FMN construct.

Journal ArticleDOI
A new pulse endor technique
TL;DR: In this paper, a new pulse technique for performing endor has been devised, which has greater sensitivity than Mims' method under certain conditions but does not suffer from "blind spots"; it also retains the normal advantages of spin echo methods.
Journal ArticleDOI
Pulsed Endor Experiments
TL;DR: In this paper, a new technique for performing electron nuclear double resonance experiments, based on the observation of electron spin echoes, has been developed, which does not depend on achieving any particular balance between relaxation rates, and has been applied in studying the Ce-W system in WO4 down to very low radio frequencies.
Journal ArticleDOI
Determination of end-to-end distances in a series of tempo diradicals of up to 2.8 nm length with a new four-pulse double electron electron resonance experiment
Rainer E. Martin,M. Pannier,François Diederich,Volker Gramlich,Michael Hubrich,Hans Wolfgang Spiess +5 more
TL;DR: A four-pulse version of the pulsed double electron electron resonance (DEER) experiment has been applied to a series of TEMPO diradicals with well-defined interradical distances ranging from 1.4 to 2.8 nm, allowing broad distributions of electron-electron distances to be measured without dead-time artifacts.
Journal ArticleDOI
Electron-nuclear double resonance spectroscopic evidence that S-adenosylmethionine binds in contact with the catalytically active [4Fe-4S](+) cluster of pyruvate formate-lyase activating enzyme.
Charles J. Walsby,Wei Hong,William E. Broderick,Jennifer Cheek,Danilo Ortillo,Joan B. Broderick,Brian M. Hoffman +6 more
TL;DR: In this article, electron paramagnetic resonance (EPR) and pulsed 35 GHz electron-nuclear double resonance (ENDOR) spectroscopy was used to investigate the effect of AdoMet on the EPR spectrum of PFL-AE.
Journal ArticleDOI
Q-Band Pulsed Electron Spin-Echo Spectrometer and Its Application to ENDOR and ESEEM
TL;DR: In this article, a homodyne electron spin-echo (ESE) spectrometer has been constructed and is described in the first section of this report and the second section presents Mims and Davies pulsed ENDOR and ESEEM applications and includes comparisons with a previously constructed X-band ESE spectrometers.
