Sulfite reductase activity in extracts of various photosynthetic bacteria.

Extracts of representative bacterial strains from the various families of photosynthetic prokaryotes are demonstrated to possess significant levels of sulfite reductase [EC 1.8.99.1; hydrogen-sulfide: (acceptor)oxidoreductase] activity with reduced methyl viologen as electron donor, but not NADPH(2). The enzyme is localized primarily in the soluble fraction of the extracts, in contrast to adeny...

Sulfite Reductase Protects Plants against Sulfite Toxicity1[W][OA]

Plant sulfite reductase (SiR; Enzyme Commission 1.8.7.1) catalyzes the reduction of sulfite to sulfide in the reductive sulfate assimilation pathway. Comparison of SiR expression in tomato (Solanum lycopersicum ‘Rheinlands Ruhm’) and Arabidopsis (Arabidopsis thaliana) plants revealed that SiR is expressed in a different tissue-dependent manner that likely reflects dissimilarity in sulfur metabo...

Flavin interaction in NADPH-sulfite reductase.

E. coli NADPH-sulfite reductase, depleted of FMN but retaining its FAD, has been prepared by photoirradiation of native enzyme in 30% — saturated ammonium sulfate. FMN-depleted enzyme loses its ability to reduce (using NADPH) ferricyanide, cytochrome c, sulfite, or the enzyme's own heme-like chromophore. However, the FAD remains rapidly reducible by NADPH, and the FMN-depleted enzyme retains NA...

Sulfur Isotope Effects of Dissimilatory Sulfite Reductase

The precise interpretation of environmental sulfur isotope records requires a quantitative understanding of the biochemical controls on sulfur isotope fractionation by the principle isotope-fractionating process within the S cycle, microbial sulfate reduction (MSR). Here we provide the only direct observation of the major ((34)S/(32)S) and minor ((33)S/(32)S, (36)S/(32)S) sulfur isotope fractio...

Analysis 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...
