Survey of the photosynthetic bacteria for rhodanese (thiosulfate: cyanide sulfur transferase) activity.
Rhodanese activity was demonstrated in extracts from all three taxonomic families of photosynthetic bacteria, and this activity appeared to be uncorrelated with thiosulfate metabolism.

پس ازفروپاشی شوروی،رشد منابع نفت و گاز، آسیای میانه و قفقاز را در یک بازی ژئوپلتیکی انرژی قرار داده است. با در نظر گرفتن این منابع هیدروکربنی، این منطقه به یک میدانجنگ و رقابت تجاری برای بازی های ژئوپلتیکی قدرت های بزرگ جهانی تبدیل شده است. روسیه منطقه را به عنوان حیات خلوت خود تلقی نموده و علاقمند به حفظ حضورش می باشد تا همانند گذشته گاز طبیعی را به وسیله خط لوله مرکزی دریافت و به عنوان یک واس...
15 صفحه اولRhodanese-catalyzed reduction of thiosulfate by reduced lipoic acid.
by a double displacement mechanism (1, 2). Thiosulfate and organic thiosulfonates will act as sulfur donors for the enzyme (3). Cyanide ion, SOS=, and the organic sulfinates will accept sulfur from the enzyme-sulfur compound (1, 4, 5). In this study, crystalline beef liver rhodanese has been found to catalyze the reduction of SSOp to HSand SOf. Several powerful reducing agents, such as NaBH4 an...
متن کاملMechanism of Rhodanese Catalysis of Thiosulfate-lipoate Oxidation-reduction.
Crystalline beef liver rhodanese (thiosulfate : cyanidesulfurtransferase, EC 2.8.1.1) catalyzes sulfur transfer from SSOato CNby a double displacement mechanism (3, 4). The biological role of this reaction is not clear, but its possible involvement in CNdetoxication has been repeatedly stressed. The present study of the specificity of the crystalline beef liver enzyme and of the occurrence of t...
متن کاملBiochemical properties and biological functions of the enzyme rhodanese in domestic animals
The enzyme rhodanese (thiosulfate: cyanide sulfurtransferase) is a ubiquitous enzyme and its activity ispresent in all living organisms. Many functions including cyanide detoxification, formation of iron-sulfurcenters and participation in energy metabolism have been attributed to this enzyme. The enzyme catalyzesthe transfer of a sulfur atom from sulfane containing compounds (such as thiosulfat...
