Identification of a gene cluster for the formation of extracellular polysaccharide precursors in the chemolithoautotroph Acidithiobacillus ferrooxidans
Article Abstract:
A cluster of five genes, proposed to be involved in the formation of extracellular polysaccharide (EPS) precursors were identified in the acidophilic autotroph Acidithiobacillus ferrooxidans. This study might provide an initial model for the metabolic pathways involved in biofilm formation in Acidithiobacillus ferrooxidans and help in understanding the role of biofilms in mineral leaching and the formation of acid mine drainage.

Regulation of a novel Acidithiobacillus caldus gene cluster involved in metabolism of reduced inorganic sulfur compounds
Article Abstract:
The regulation of a new cluster containing the gene encoding tetrathionate hydrolase (tetH), a key enzyme in the reduced inorganic sulfur compounds (RISCs) metabolism, is described. A pyrrolo-quinone binding domain in TetH is predicted by bioinformatic analysis and the presence of an o-quinone moiety is verified, thereby suggesting a mechanism for tetrathionate oxidation.
