title: [Enzymes involved in thiosulfate metabolism in Thiocapsa roseopersicina under various conditions of growth].
abstract: Cell-free preparations of the purple sulphur bacterium Thiocapsa roseopersicina grown in the light under anaerobic conditions and in the dark under aerobic conditions contain thiosulphate reductase and rhodanase. Dihydrolipoate is an electron donor in the cleavage of thiosulphate catalysed by thiosulphate reductase. Lipoate dehydrogenase (NADH: lipoate oxidoreductase) found in extracts of the cells of T. roseopersicina catalyses the reduction of lipoate. The activity of the enzymes involved in thiosulphate metabolism increases in the cells of T. roseopersicina growing under aerobic conditions in the dark on a mineral medium containing thiosulphate.
