Sulfur is very relevant for oxidative stress defense, as the thiol group in the redox-active molecules glutathione, thioredoxin, peroxiredoxin and ergothioneine is fundamental for their activity (Ulrich and Jakob, 2019). Sulfur is also fundamental for methylation reactions, as it is an integral ...
It is possible to roughly divide the main representatives of sulfate reducers involved in the corrosion into two groups, according to the temperature: (1) a group normally described in an environment with low temperatures, with emphasis on the genera Desulfovibrio, Desulfovermiculus, Desulfomicrobiu...
sulfur (S), nonmetallic chemical element belonging to the oxygen group (Group 16 [VIa] of the periodic table), one of the most reactive of the elements. Pure sulfur is a tasteless, odourless, brittle solid that is pale yellow in colour, a poor conductor of electricity, and insoluble in ...

and sulfide toxicity.S. alterniflora-dominated salt marsh ecosystems represent an ideal natural laboratory in which to study the effects of stress on plant-microbe interactions because steep gradients in plant productivity are formed within short distances20. The productivity gradient is the result of ...
However, it is not clear how tomato plants physiologically respond to V. dahliae infection and what roles sulfur plays in the disease-resistance. Pot experiments were performed to examine changes in the physiology and sulfur metabolism of tomato roots infected by V. dahliae under the companion ...
It is a herbicide belonging to the class of sulfonylureas. It appears as a white crystalline solid with no distinct odor. Its basic structure consists of a chlorine atom, a methyl group, and a sulfonamide group attached to a central carbon atom. This compound is soluble in water. Halosulfur...
Davis, R. Thimma Reddy, in Comprehensive Heterocyclic Chemistry II, 1996 1.12.3.6.3.(iii) Oxidation of thiols to sulfenic acids The biological activity of thiols depends, to a large extent, on the facility with which the SH group is oxidized to high sulfur oxides (RSOxH) and disulfides (...
(i) an additional domain of variable size, Domain V, that plays an essential role in defining the substrate binding funnel; (ii) an N-terminal Cys group located in Domain I that provides coordination to the [Fe-S] cluster (FS0) of the ETR that is closest to the Mo-bisPGD cofactor....
