Regulation of the aerobic respiratory chain in the facultatively aerobic and hyperthermophilic archaeon Pyrobaculum oguniense

Article Abstract:

Results show that the aerobic respiratory pathway is expressed in anaerobic Pyrobaculum oguniense. Data indicate that the transcription of the gene cluster of SoxB-type haem-copper oxidase and cytochrome bc complex occurs both in aerobic and anaerobic conditions.
