Protein Domain : Cytochrome b5, heme-binding site IPR018506

Type  Binding_site
Description  Cytochromes b5 are ubiquitous electron transport proteins found in animals, plants and yeasts []. The microsomal and mitochondrial variants are membrane-bound, while those from erythrocytes and other animal tissues are water-soluble [ , ]. The 3D structure of bovine cyt b5 is known, the fold belonging to the alpha+beta class, with 5 strands and 5 short helicesforming a framework for supporting a central haem group [ ]. The cytochrome b5 domain is similar to that of a numberof oxidoreductases, such as plant and fungal nitrate reductases, sulphite oxidase, yeast flavocytochrome b2 (L-lactate dehydrogenase) and plant cyt b5/acyl lipid desaturasefusion protein. This conserved site includes the first of the two histidine heme ligands, which are found in the heme-binding domain of cytochrome b5 family.
