A Simplifed Functional Version of the Escherichia coli Sulfite Reductase [PDF]

open access: yesJournal of Biological Chemistry, 2000
Escherichia coli sulfite reductase (SiR) is a large and soluble enzyme with an alpha(8)beta(4) quaternary structure. Protein alpha (or sulfite reductase flavoprotein) contains both FAD and FMN, whereas protein beta (or sulfite reductase hemoprotein (SiR-HP)) contains an iron-sulfur cluster coupled to a siroheme.

Metatranscriptomic analysis of sulfur oxidation genes in the endosymbiont of Solemya velum

open access: yesFrontiers in Microbiology, 2011
Thioautotrophic endosymbionts in the Domain Bacteria mediate key sulfur transformations in marine reducing environments. However, the molecular pathways underlying symbiont metabolism and the extent to which these pathways are expressed in situ are ...

FdC1 and Leaf-Type Ferredoxins Channel Electrons From Photosystem I to Different Downstream Electron Acceptors

open access: yesFrontiers in Plant Science, 2018
Plant-type ferredoxins in Arabidopsis transfer electrons from the photosystem I to multiple redox-driven enzymes involved in the assimilation of carbon, nitrogen, and sulfur.

Molecular and Phenotypic Characterization of Metschnikowia pulcherrima Strains from Douro Wine Region

open access: yesFermentation, 2018
Some non-Saccharomyces yeasts, including Metschnikowia pulcherrima, have been proposed as selected starters due to their contribution for the overall aroma and chemical profiles of wines.

New insights into metabolic properties of marine bacteria encoding proteorhodopsins.

open access: yesPLoS Biology, 2005
Proteorhodopsin phototrophy was recently discovered in oceanic surface waters. In an effort to characterize uncultured proteorhodopsin-exploiting bacteria, large-insert bacterial artificial chromosome (BAC) libraries from the Mediterranean Sea and Red ...

Hibiscus chlorotic ringspot virus Coat Protein Upregulates Sulfur Metabolism Genes for Enhanced Pathogen Defense

open access: yesMolecular Plant-Microbe Interactions, 2012
In both Hibiscus chlorotic ringspot virus (HCRSV)-infected and HCRSV coat protein (CP) agroinfiltrated plant leaves, we showed that sulfur metabolism pathway related genes—namely, sulfite oxidase (SO), sulfite reductase, and adenosine 5′-phosphosulfate ...

The Sulfur Oxygenase Reductase Activity Assay: Catalyzing a Reaction with Elemental Sulfur as Substrate at High Temperatures

open access: yesBio-Protocol, 2017
The sulfur oxygenase reductase (SOR) reaction is a dioxygen-dependent disproportionation of elemental sulfur (S0), catalyzed at optimal temperatures between 65 °C and 85 °C. Thiosulfate and sulfite are formed as oxidized products as well hydrogen sulfide

The Iron-Sulfur Flavoprotein DsrL as NAD(P)H:Acceptor Oxidoreductase in Oxidative and Reductive Dissimilatory Sulfur Metabolism

open access: yesFrontiers in Microbiology, 2020
DsrAB-type dissimilatory sulfite reductase is a key enzyme of microbial sulfur-dependent energy metabolism. Sulfur oxidizers also contain DsrL, which is essential for sulfur oxidation in Allochromatium vinosum.

Lateral Gene Transfer of Dissimilatory (Bi)Sulfite Reductase Revisited [PDF]

open access: yesJournal of Bacteriology, 2005
ABSTRACT In contrast to previous findings, we demonstrate that the dissimilatory (bi)sulfite reductase genes ( dsrAB ) of Desulfobacula toluolica were vertically inherited. Furthermore, Desulfobacterium anilini and strain mXyS1 were identified, by
