The Metabolism of Thiosulfate in Salmonella Typhimurium.
Inorganic thiosulfate has been implicated as an intermediate in the assimilation of sulfate in a variety of organisms. Nutritional studies with mutants of Aspergillus have been interpreted to indicate thiosulfate as an intermediate between sulfite and cysteine (1, 2), possibly via a pathway involving cysteine-Ssulfonate as a direct precursor of cyst&e (24). Shepherd earlier had envisioned the u...
متن کاملPurification and properties of trimethylamine oxide reductase from Salmonella typhimurium.
The major inducible trimethylamine oxide reductase was purified from Salmonella typhimurium LT2. The molecular weights of the native enzyme were estimated to be 332,000 by gel filtration and 170,000 by nondenaturing disc gel electrophoresis. In sodium dodecyl sulfate-gel electrophoresis, the enzyme formed a single band of molecular weight 84,000. The isoelectric point was 4.28. Maximum activity...
متن کاملThiosulfate reductase isolated from Desulfotomaculum nigrificans.
A thiosulfate reductase from Desulfotomaculum nigrificans has been partially purified by ammonium sulfate fractionation, diethylaminoethylcellulose chromatography, and sucrose density gradient centrifugation. With inner-and outer-labeled (35)S-thiosulfate, the enzyme reduced only the outer sulfur atom to hydrogen sulfide. The enzyme was inhibited by sulfite and also by several sulfhydryl inhibi...
متن کاملAnalysis of nitrate reductase mRNA expression and nitrate reductase activity in response to nitrogen supply
Nitrate is one of the major sources of nitrogen for the growth of plants. It is taken up by plant roots and transported to the leaves where it is reduced to nitrite in the. The main objective of this research was to investigate stimulatory effects of sodium nitrate, potassium nitrate, ammonia and urea on the production/generation of the nitrate reductase mRNA in Triticum aestivum plants. The pl...
متن کاملCharacterization of the chlorate reductase from Pseudomonas chloritidismutans.
A chlorate reductase has been purified from the chlorate-reducing strain Pseudomonas chloritidismutans. Comparison with the periplasmic (per)chlorate reductase of strain GR-1 showed that the cytoplasmic chlorate reductase of P. chloritidismutans reduced only chlorate and bromate. Differences were also found in N-terminal sequences, molecular weight, and subunit composition. Metal analysis and e...
