Cytochromes and some respiratory enzymes in mitochondria from the spadix of Arum maculatum.
5. A Fe2+ ion-ethylenediaminetetra-acetic acid complex can catalyse the oxidative formation of an inhibitor from schradan. 6. A mechanism for the simultaneous oxidation of schradan and reduced triphosphopyridine nucleotide is suggested. 7. The requirements for the conversion of dimefox to an anti-esterase are the same as those for schradan, but the rate of esterase inhibition is much higher. Di...
متن کاملIron-sulphur centres in mitochondria from Arum maculatum spadix with very high rates of cyanide-resistant respiration.
X-band electron-paramagnetic-resonance spectroscopy at 4.2--77K combined with measurements of oxidation-reduction potential was used to identify iron--sulphur centres in Arum maculatum (cuckoo-pint) mitochondria. In the oxidized state a signal with a derivative maximum at g = 2.02 was assigned to succinate dehydrogenase centre S-3. Unreduced particles showed additional signals at g = 2.04 and 1...
متن کاملIsolation and properties of a flavoprotein from heart muscle tissue.
SrNcE Warburg & Christian [1932] isolated the first flavoprotein from yeast (flavinphosphoric acid as its prosthetic group) and Banga & Szent-Gyorgyi [1932] observed the presence of flavin in muscle tissue, there has been much speculation on the possible role of a flavoprotein in the mechanism of oxidations in animal tissues. As yet, however, there is no information on the state and function of...
متن کاملProperties of anthranilate hydroxylase (deaminating), a flavoprotein from Trichosporon cutaneum.
Anthranilate hydroxylase was purified from the yeast Trichosporon cutaneum. This enzyme is a simple flavoprotein which apparently does not require any additional cofactor for the conversion of anthranilate to 2,3-dihydroxybenzoate. Anthranilate hydroxylase has Mr of approximately 95,000, with subunit Mr of 50,000; it contains 2 mol of FAD/mol of enzyme. A number of compounds in addition to anth...
متن کاملLactose dehydrogenase, a new flavoprotein.
lengths when oxidation of the intermediate was carried out in amino acids, ar-keto acids, or ammonia. It is not observed the absence of excess substrate. Reduction of the enzyme by when relatively high concentrations of oxygen are present, since other substrates (e.g. L-phenylalanine, L-alanine, L-valine) or by under these conditions the intermediate presumably has only dithionite, followed by ...
