Bioenergetics of the archaebacterium Sulfolobus

摘要: Archaea are forming one of the three kingdoms defining universal phylogenetic tree living organisms. Within itself this kingdom is heterogenous regarding mechanisms for deriving energy from environment support cellular functions. These comprise fermentative and chemolithotrophic pathways as well light driven respiratory conservation. Due to their extreme growth conditions access molecular machineries transduction in archaea can be experimentally limited. Among aerobic, thermoacidophilic archaea, genus Sulfolobus has been studied greater detail than many others provides a comprehensive picture bioenergetics on level substrate metabolism, formation utilization high phosphate bonds, primary conservation electron transport. A number novel metabolic reactions unusual structures enzyme complexes have detected. Since genomic organization other could determined, these studies shed evolution various bioenergetic modules. It aim review bring different aspects into focus representative example of, point comparison closely related, aerobic archaea.
