In situ Spectroscopy on Intact Leptospirillum ferrooxidans Reveals that Reduced Cytochrome 579 is an Obligatory Intermediate in the Aerobic Iron Respiratory Chain
Electron transfer reactions among colored cytochromes in intact bacterial cells were monitored using an integrating cavity absorption meter that permitted the acquisition of accurate absorbance data in suspensions of cells that scatter light. The aerobic iron respiratory chain of Leptospirillum ferrooxidans was dominated by the redox status of an abundant cellular cytochrome that had an absorba...
متن کاملDraft Genome Sequence of the Iron-Oxidizing Acidophile Leptospirillum ferriphilum Type Strain DSM 14647
The genomic features of the Leptospirillum ferriphilum type strain DSM 14647 are described here. An analysis of the predicted genes enriches our knowledge of the molecular basis of iron oxidation, improves our understanding of its role in industrial bioleaching, and suggests how it is adapted to live at extremely low pH.

15 صفحه اولCharacterization of cytochrome 579, an unusual cytochrome isolated from an iron-oxidizing microbial community.
A novel, soluble cytochrome with an unusual visible spectral signature at 579 nm (Cyt(579)) has been characterized after isolation from several different microbial biofilms collected in an extremely acidic ecosystem. Previous proteogenomic studies of an Fe(II)-oxidizing community indicated that this abundant red cytochrome could be extracted from the biofilms with dilute sulfuric acid. Here, we...
