Abstract

DNA sequence analysis and bioinformatic interpretations have identified two adjacent clusters of genes potentially involved in the formation of a bc1 complex and in the maturation of a cytochrome c-type protein in two strains (ATCC 19859 and ATCC 33020) of the acidophilic, chemolithoautotrophic bacterium Acidithiobacillus ferrooxidans (formerly Thiobacillus ferrooxidans). Reverse transcriptase-PCR experiments suggest that the two clusters are organized as operons, and +1 start sites of transcription for the operons have been determined by primer extension experiments. Potential promoters have been identified. The presence of these operons lends support to a recent model of reverse electron flow and is consistent with previous reports of phenotypic switching in this bacterium.
