Cyanide-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 - insensitive Respiration in Plant Mitochondrial
Pathways of electron transport have been studied in mitochondria isolated from hypocotyls of etiolated mung bean seedlings and skunk cabbage spadices that show cyanide-resistant respiratory activity. The residual flux through cytochrome c oxidase is shown to be small in comparison with the flux through an unidentified alternative oxidase that is known to have a high affinity for oxygen. This al...
متن کاملInduction of cyanide-insensitive respiration in Neurospora crassa.
Treatment of cultures of Neurospora crassa with chloramphenicol results in the appearance of a mitochondrial respiratory pathway that is insensitive to cyanide and antimycin A but is inhibited by salicylhpdroxamic acid. Under the experimental conditions employed, protein(s) required for the expression of the alternate pathway is synthesized on cytoplasmic ribosomes at a constant rate for 2.5 ho...
متن کاملIdentification of the quinone species in cyanide-sensitive and cyanide-insensitive mitochondria of Moniliella tomentosa.
Moniliella tomentosa was investigated for the presence of different quinones that might be involved in the cyanide-sensitive and/or cyanide-insensitive electron-transport pathways. The naturally occurring quinone in Moniliella tomentosa was found to be ubiquinone-45. Other quinone species could not be detected. The concentration of ubiquinone-45 in mitochondria is not related to the presence or...
متن کاملOxygen consumption and luminescence of Porichthys photophores stimulated by potassium cyanide.
Isolated photophores of Porichthys notatus, maintained in saline at 20 degrees C, do not luminesce and show an oxygen consumption rate of 0.07 +/- 0.01 nmol min-1 photophore-1. In the presence of 10(-6) M-KCN, the photophores do not luminesce but the resting respiration decreases by about 50%. In the presence of 10(-5) M-KCN, some photophores do not luminesce and their respiration rate decrease...
