Electron paramagnetic resonance studies on Pseudomonas nitrosyl nitrite reductase. Evidence for multiple species in the electron paramagnetic resonance spectra of nitrosyl haemoproteins.
The e.p.r. spectra of reduced 14NO- and 15NO-bound Pseudomonas nitrite reductase have been investigated at pH 5.8 and 8.0 in four buffer systems. At pH 8.0, absorption spectra indicated that only the haem d1 was NO-bound, but, although quantification of the e.p.r. signals in all cases accounted for NO bound the the haem d1 in both subunits of the enzyme, the precise form of the signals varied w...
متن کاملElectron paramagnetic resonance studies of nitrosyl ferrous heme complexes. Determination of an equilibrium between two conformations.
Ferrous hemeproteins and inorganic heme complexes react with nitric oxide to form six-coordinate paramagnetic complexes. These complexes exhibit strong EPR signals centered near g = 2.0 which are easily observed in frozen solution. We have obtained EPR spectra of the nitrosyl adducts of Fe(II) protoporphyrin IX-imidazole in dimethylsulfoxide and in dimethylformamide, and of myoglobin, cytochrom...
متن کاملElectron Paramagnetic Resonance and Oxygen Binding Studies of a-Nitrosyl Hemoglobin
a-Nitrosyl hemoglobin, a(Fe-NO)2b(Fe)2, which is frequently observed upon reaction of deoxy hemoglobin with limited quantities of NO in vitro as well as in vivo, has been synthetically prepared, and its reaction with O2 has been investigation by EPR and thermodynamic equilibrium measurements. a-Nitrosyl hemoglobin is relatively stable under aerobic conditions and undergoes reversible O2 binding...
متن کاملStudies on dihydroorotate dehydrogenase by electron paramagnetic resonance spectroscopy. II. Electron paramagnetic resonance and optical spectra and titrations.
When dihydroorotate dehydrogenase, from Zymobacterium oroticum, was reduced by DPNH or dihydroorotate and examined by electron paramagnetic resonance spectrometry, a relatively intense free radical signal and the asymmetric signal at g = 1.94, found in many nonheme iron proteins, were observed within a few milliseconds. Both shape and saturation with microwave power of the free radical signals ...
متن کاملElectron paramagnetic resonance properties of liver fluke (Dicrocoelium dendriticum) nitrosyl hemoglobin.
The electron paramagnetic resonance properties of the nitric oxide derivative of liver fluke (Dicrocoelium dendriticum) hemoglobin (DD-Hb) have been investigated in the pH range from 4.8 to 7.8. In the neutral and alkaline regions the spectra have a rhombic shape, with gx = 2.09, gy = 1.99 and gz = 2.009, and a triplet hyperfine structure of 2.2 mT, due to the nitrogen of the bound NO molecule,...
