Prokaryotic sulfur oxidation

Cornelius G Friedrich et al. Curr Opin Microbiol. 2005 Jun.

Abstract

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 encoding sulfur dehydrogenase. This indicates a different pathway for oxidation of sulfur to sulfate. Acidophilic bacteria oxidize sulfur by a system different from the Sox enzyme system, as do chemotrophic endosymbiotic bacteria.
