Prokaryotic sulfur oxidation

Current Opinion in Microbiology, 2005
Recent biochemical and genomic data differentiate the sulfur oxidation pathway of Archaea from those of Bacteria. From these data it is evident that members of the Alphaproteobacteria harbor the complete sulfur-oxidizing Sox enzyme system, whereas members of the beta and gamma subclass and the Chlorobiaceae contain sox gene clusters that lack the genes

Sulfur Species in Graphene Oxide

Chemistry – A European Journal, 2013
AbstractThe structure of graphene oxide (GO) is of crucial importance for its chemical functionalization. However, the sulfur content present in GO prepared by Hummers’ method has only been addressed by a few authors so far. It has been reported that hydrolysis of sulfur species takes place and that stable sulfonic groups are present in graphite oxide.

Effects of sulfur oxides on eicosanoids

Journal of Toxicology and Environmental Health, 1989
Ultrafine metal oxides and SO2 react during coal combustion or smelting operations to form primary emissions coated with an acidic SOx layer. Ongoing work in this laboratory has examined the effects of sulfur oxides on pulmonary functions of guinea pigs.

Inorganic sulfur oxidizing system in green sulfur bacteria

Photosynthesis Research, 2010
Green sulfur bacteria use various reduced sulfur compounds such as sulfide, elemental sulfur, and thiosulfate as electron donors for photoautotrophic growth. This article briefly summarizes what is known about the inorganic sulfur oxidizing systems of these bacteria with emphasis on the biochemical aspects.

Cytoplasmic sulfur trafficking in sulfur‐oxidizing prokaryotes

IUBMB Life, 2015
AbstractPersulfide groups are chemically versatile and participate in a wide array of biochemical pathways. Although it is well documented that persulfurated proteins supply a number of important and elaborate biosynthetic pathways with sulfane sulfur, it is far less acknowledged that the enzymatic generation of persulfidic sulfur, the successive ...

The stereochemistry of oxidation at sulfur

Tetrahedron, 1969
Abstract Oxidation of 2-thiabicyclo[2.2.1]heptane by a variety of oxidizing agents provided both endo and exo sulfoxides. The ratio of these sulfoxide isomers is a function of the relative stability of the sulfoxides and/or the mechanism of the oxidation reaction.
