Cytochrome b5 B/CYB5B Protein(C-6His) (recombinant human)

Protein Construction: Recombinant Human Cytochrome b5 type B is produced by our Mammalian expression system and the target gene encoding Lys12-Cys118 is expressed with a 6His tag at the C-terminus. Sequence: Lys12-Cys118. Fusion tag: C-6His Endotoxin: < 1.0 EU per µg as determined by the LAL method. Apparent Molecular Mass: 22 kDa. Protein function: Cytochrome b5 type B (CYB5B) is a membrane of the cytochrome b5 family. It contains 1 cytochrome b5 heme-binding domain. Cytochrome b5 is a membrane bound hemoprotein which function as an electron carrier for several membrane bound oxygenases. In the mitochondrion of eukaryotes and in aerobic prokaryotes, cytochrome b is a component of respiratory chain complex III also known as the bc1 complex or ubiquinol-cytochrome c reductase. Protein function: Cytochrome b5 is a membrane bound hemoprotein which function as an electron carrier for several membrane bound oxygenases. [The UniProt Consortium]
