Description | Succinate dehydrogenase (SDH) is a membrane-bound complex of two main components: a membrane-extrinsic component composed of an FAD-binding flavoprotein and an iron-sulphur protein, and a hydrophobic component composed of a cytochrome b and a membrane anchor protein. The cytochrome b component is a mono-haem transmembrane protein [ , , ] belonging to a family that includes:Cytochrome b-556 from bacterial SDH (gene sdhC).Cytochrome b560 from the mammalian mitochondrial SDH complex, which is encoded in the mitochondrial genome of some algae and in the plant Marchantia polymorpha.Cytochrome b from yeast mitochondrial SDH complex (gene SDH3 or CYB3).Protein cyt-1 from Caenorhabditis elegans.These cytochromes are proteins of about 130 residues that comprise three transmembrane regions. There are two conserved histidines which may be involved in binding the haem group. | Name | Succinate dehydrogenase, cytochrome b subunit, conserved site |
