EPR and Mössbauer studies of benzoyl-CoA reductase.
Benzoyl-CoA reductase catalyzes the two-electron transfer from a reduced ferredoxin to the aromatic ring of benzoyl-CoA; this reaction is coupled to stoichiometrical ATP hydrolysis. A very low reduction potential (less than -1 V) is required for the first electron transfer to the aromatic ring. In this work the nature of the redox centers of purified benzoyl-CoA reductase from Thauera aromatica...
متن کاملMössbauer Spectroscopic Studies of Monosubstituted Pentacyano Ferrate ( II ) Complexes ,
Mössbauer Spectra, Hexacoordinate Complexes A series of compounds Na3[Fe(CN)5RNH2] * nH 20 where R = -H, -CH3, -C2H5, n-C3H7, n-C4H9 and -CH2C6H5 and RNH2 = C5H5N have been studied by Mössbauer spectroscopy. Quadrupole splitting (A EQ) values vary in a limited range (0.68-0.80 mm/sec) indicating only small distortions in the octahedral geometry of the compounds with the substitution of various ...
متن کاملChloroperoxidase 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 کاملPreparation and NMR, Mass and Mössbauer Studies of Di-and Triorganotin (IV) Derivatives of 3-(2-Furanyl)-2- Propenoic Acid
3-(2-Furanyl)-2-propenoic acid has been used to prepare a new series of organotin complexes of general formula R3SnL (R=Me, Et, n-Bu, Ph and Cy) and R2SnL2 (R=Me and n-Bu). These complexes have been characterized by elemental analyses, IR, 1H-NMR, MASS and Mössbaure spectroscopy.
متن کاملpostnatal studies of bats (pipistrellus kuhlii and miniopterus schreibersii) & histomorphology and histochemistry studies of organs and diseases of (neurergus microspilotus and n. kaiseri)
1. to determine whether difference in birth body mass influenced growth performance in pipistrellus kuhlii we studied a total of 12 captive-born neonates. bats were assigned to two body mass groups: light birth body mass (lbw: 0.89 ± 0.05, n=8) and heavy birth body mass (hbw: 1.35 ± 0.08, n=4). heavier body mass at birth was associated with rapid postnatal growth (body mass and forearm length) ...
