TL;DR: The isolation of Candidatus “Nitrosopumilus maritimus” strain SCM1 is reported, revealing highly copper-dependent systems for ammonia oxidation and electron transport that are distinctly different from known ammonia-oxidizing bacteria.
Journal ArticleDOI
The cytochrome bd respiratory oxygen reductases
TL;DR: Current knowledge on the physiological functions, genetics, structural and catalytic properties of cytochromes bd, a respiratory quinol: O₂ oxidoreductase found in many prokaryotes, is summarized.
Journal ArticleDOI
Evolution of Oxygenic Photosynthesis
TL;DR: Critically review and synthesize information from the geological and biological records for the origin and evolution of oxygenic photosynthesis, facilitating much of the richness the authors associate with modern biology, including complex multicellularity.
Journal ArticleDOI
On the origins of oxygenic photosynthesis and aerobic respiration in Cyanobacteria
TL;DR: It is shown that all three classes of Cyanobacteria independently acquired aerobic respiratory complexes, supporting the hypothesis that aerobic respiration evolved after oxygenic photosynthesis.
Journal ArticleDOI

TL;DR: The genome of Sulfurimonas denitrificans DSM1251 was sequenced in this article, showing a branched electron transport chain with genes encoding complexes for the oxidation of hydrogen, reduced sulfur compounds, and formate and the reduction of nitrate and oxygen.
