Protein Domain : Cytochrome b558/566, subunit B IPR017573

Type	Family
Description	This entry represents CbsB, a hydrophobic protein which is found in Sulfolobus acidocaldarius and several other members of the Sulfolobales, a branch of the Crenarchaeota [ , ]. Encoded at the same locus as CbsB are: CbsA, a high potential cytochrome b558/566, SoxL, a Rieske iron-sulphur protein, SoxN, a predicted membrane-bound b-type cytochrome b, and OdsN, a protein of unknown function. Transcriptional studies suggest that these proteins may form a complex analogous to the cytochrome bc1 complex. The redox-active subunits of this complex would consist of CbsA, SoxL and SoxN, while CbsB and OdsN would be additional non-redox-active subunits. A possible function for CbsB, based on its hydrophobicity, would be to anchor CbsA to the membrane.
Short Name	Cyt_b558/566_suB
