Acidithiobacillus ferrooxidans	quantitative 2D-PAGE proteomic analysis of a resting cell suspension of a sulfur-grown Acidithiobacillus ferrooxidans CCM 4253 subculture that has lost its iron-reducing activity reveals that 147 protein spots are downregulated relative to an iron-reducing resting cell suspension of the antecedent sulfur-oxidizing culture and 111 are upregulated. Gene cyc2 encoding the enzyme is strongly downregulated	down

General Information

General Information	Comment	Organism
evolution	exclusive sulfur oxidizers such as Acidithiobacillus thiooxidans and Acidithiobacillus caldus cannot oxidize S0 under anaerobic conditions. The ability to facultatively oxidize S0 with Fe3+ as the electron acceptor in oxygen-limited environments has only been demonstrated in sulfur and iron oxidizers such as Acidithiobacillus ferrooxidans, Acidithiobacillus ferridurans, Acidithiobacillus ferrivorans and Acidithiobacillus ferriphilus strains, all previously generally classified as different strains of Acidithiobacillus ferrooxidans (Group I-IV)	Acidithiobacillus ferrooxidans
metabolism	the main anaerobic respiratory pathway includes the cytochrome bc1 complex I, a c4-type cytochrome, rusticyanin, and Cyc2 as the terminal reductase. Analysis of Fe3+-reducing activity of Acidithiobacillus ferrooxidans strain CCM 4253 phenotypes in resting cell suspension cultures, transcriptomic and proteomic analysis and modeling of wild-type and of S0-grown subcultures that have lost the ability to reduce Fe3+, overview	Acidithiobacillus ferrooxidans
