Deficiency of thiosulphate sulphurtransferase (rhodanese) in Leber's hereditary optic neuropathy.
Leber's hereditary optic neuropathy is a rare cause of progressive visual failure. Its cause is unknown, but one hypothesis is that patients have a defect in the detoxication of cyanide. One of the enzymes used in this detoxication is thiosulphate sulphurtransferase (rhodanese). The activity of this enzyme was measured in the rectal mucosa of a group of subjects with Leber's hereditary optic ne...
متن کاملCarbon metabolism in Chromatium.
The purple photosynthetic sulfur bacterium, Chromatium, will grow only in the light and under anaerobic conditions. This organism can grow on an inorganic medium utilizing CO2 as the sole carbon source in the presence of reduced inorganic sulfur compounds. Some reduced carbon compounds can be utilized for the growth of this organism but only in the light and under anaerobic conditions. In this ...
متن کاملMolecular cloning, sequencing and characterization of cDNA to rat liver rhodanese, a thiosulphate sulphurtransferase.
Rhodanese (EC 2.8.1.1), a mitochondrial thiosulphate sulphurtransferase, is involved in the formation of iron-sulphur complexes and cyanide detoxification. By screening a rat liver cDNA library with oligonucleotide probes complementary to portions of the published bovine rhodanese peptide sequence, rat rhodanese cDNA clones were obtained and sequenced. Comparison of the rat rhodanese cDNA open ...
متن کاملCoproporphyrinogenase activities in extracts of Rhodopseudomonas spheroides and Chromatium strain D.
1. The anaerobic coproporphyrinogenase activity in an extract of Rhodopseudomonas spheroides is inhibited by 1,10-phenanthroline, alphaalpha'-bipyridyl, flavins, 2,4-dinitrophenol and 1,4-naphthaquinone. These compounds have no effect on the aerobic coproporphyrinogenase activity. 2. On removal of small-molecular-weight material from a crude extract, the anaerobic system becomes very unstable; ...
متن کاملSeparation and identification of the polar lipids of Chromatium strain D.
The polar lipids of the autotrophically grown, obligately anaerobic, photosynthetic bacterium Chromatium strain D were separated by paper chromatography. Four major phospholipids were identified: lysophosphatidylethanolamine, phosphatidylethanolamine, phosphatidylglycerol, and cardiolipin. In addition, three glycolipids were observed and characterized, namely, monoglucosyldiglyceride, which is ...
