Heme Spin Distribution in the Substrate-Free and Inhibited Novel CYP116B5hd: A Multifrequency HYSCORE Study

§  Data type: Experimental spectroscopic measurements, computer simulations. §  Files are with filename extensions: .DSC, .DAT, .m §  Information on origin of the data: o   EPR spectroscopic measurements with filename extensions .DSC, .DTA and .txt. o   EPR spectroscopic simulation based on Easyspin with filename extension .m. §  CW and Pulse X-band experiments were performed on a Bruker ELEXSYS E580 X-band spectrometer (microwave frequency 9.68 GHz) equipped with a cylindrical dielectric cavity and a helium gas-flow cryostat from Oxford Inc. Q-band Pulse EPR experiments were performed on a Bruker ELEXSYS E580 spectrometer (microwave frequency 34 GHz) equipped with a continuous helium flow cryostat from Oxford Inc. The magnetic field was measured by means of a Bruker ER035M NMR gaussmeter. ENDOR experiments were carried out with a Bruker ESP 380E spectrometer (X-band) equipped with an EN 4118X-MD4 Bruker resonator. §  If the dataset includes multiple files that relate to each other: o   Files in PARACAT_WP5_20240112_CW folder includes X-band CW-EPR spectroscopic measurements, original data are in .DTA and .DSC formats. o   Files in PARACAT_WP5_20240112_EDFS folder includes echo detected field sweep (EDFS) spectroscopic measurements, original data are in .DTA and .DSC formats. o   Files in PARACAT_WP5_20240112_HYSCORE folder includes HYSCORE spectroscopic 2D measurements, original data are in .DTA and .DSC formats. o   Files in PARACAT_WP5_20240112_ENDOR folder includes ENDOR spectroscopic measurements, original data are in .txt format. o   Files in PARACAT_WP5_20240112_MATLAB folder includes computer simulations/analyses of the EPR measurements, data are in .m format. §  Information on: o   Specialized abbreviations: EPR – Electron Paramagnetic Resonance, CW – Continuous Wave-EPR, HYSCORE – HYperfine Sublevel CORrelation, ENDOR - Electron Nuclear DOuble Resonance, CYP450 – Cytochrome P450. o   Definitions of variables: Magnetic field, Temperature. o   Units of measurement: Gauss (G), milliTesla (mT), Kelvin (K).
