Aquifex aeolicus is a microaerophilic hydrogen- and sulfur -oxidizing bacterium that assimilates CO2 via the reverse tricarboxylic acid cycle (rTCA). Key enzymes of this pathway are pyruvate:ferredoxin oxidoreductase (PFOR) and 2-oxoglutarate:ferredo

Autor: Sébastien Le Laz, Arlette Kpebe, Marielle Bauzan, Sabrina Lignon, Marc Rousset, Myriam Brugna
Publikováno v: PLoS ONE, Vol 9, Iss 1, p e86343 (2014)
The genome of the facultative anaerobic γ-proteobacterium Shewanella oneidensis MR-1 encodes for three terminal oxidases: a bd-type quinol oxidase and two heme-copper oxidases, a A-type cytochrome c oxidase and a cbb 3-type oxidase. In this study, w
