Chloroperoxidase compound I: Electron paramagnetic resonance and Mössbauer studies.
The green primary compound of chloroperoxidase was prepared by freeze-quenching the enzyme after rapid mixing with a 5-fold excess of peracetic acid. The electron paramagnetic resonance (EPR) spectra of these preparations consisted of at least three distinct signals that could be assigned to native enzyme, a free radical, and the green compound I as reported earlier. The absorption spectrum of ...
متن کاملElectron Paramagnetic Resonance Studies of the Effects of π-donor Ligand and B18N18 Nanoring Field on Energy Gaps
To investigation non-bonded interaction of the [CuF4]2- complex inside nanoring, we focus on the single wall boron-nitride B18N18 nanoring. Thus, the geometry of B18N18 nanoring has been optimized by B3LYP method with EPR-II basis set and geometry of the [CuF4]2- complex has been optimized at B3LYP method with Def2-TZVP basis set and Stuttgart RSC 1997 Effective Core Potential. Also electronic ...

متن کاملelectron-paramagnetic-resonance studies using oxygen-17
Studies of the effect of substitution with 170 on the e.p.r. spectra at 9 and 35 GHz of Mo(V) in the phosphate complex of sulphite oxidase are reported. Substitution of '7O-enriched water for normal water, for samples of the enzymes reduced by sulphite in the presence of normal phosphate, produced no detectable effect on the e.p.r. signal. If phosphate substituted with 170 was used, coupling du...
