Iron-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 کاملEffects of Cyanide and Ethylene on the Respiration of Cyanide-sensitive and Cyanide-resistant Plant Tissues.
The effects of cyanide and ethylene, respectively, were studied on the respiration of a fully cyanide-sensitive tissue-the fresh pea, a slightly cyanide-sensitive tissue-the germinating pea seedling, and a cyanide-insensitive tissue-the cherimoya fruit. Cyanide inhibition of both fresh pea and pea seedling respiration was attended by a conventional Pasteur effect where fermentation was enhanced...
متن کاملCycloheximide stimulation of cyanide-resistant respiration in suspension cultures of senescent pear fruit cells.
Pear fruit cells undergoing a period of senescence in auxin-deprived media develop a substantial cyanide resistant respiration in response to the addition of 0.7 to 3.5 micromolar cycloheximide. The inhibitor does not affect overall cellular repiratory activity and titrations with salicylhydroxamic acid reveal that only a minor portion, about 10%, of the alternate pathway is utilized by the cyc...
متن کاملCyanide-insensitive Respiration in Pea Cotyledons.
Mitochondria isolated by a zonal procedure from the cotyledons of germinating peas possessed a cyanide-resistant respiration. This respiration was virtually absent in mitochondria isolated during the first 24 hours of germination but thereafter increased gradually until the 6th or 7th day of seedling development. At this time between 15 and 20% of the succinate oxidation was not inhibited by cy...
متن کاملCyanide-resistant respiration in Neurospora crassa.
Cell respiration in wild type and poky was studied as part of a long-term investigation of cyanide-resistant respiration in Neurospora. Respiration in wild type proceeds via a cytochrome chain which is similar to that of higher organisms; it is sensitive to antimycin A or cyanide. Poky, on the other hand, respires by means of two alternative oxidase systems. One of these is analogous to the wil...
