CYB5A, also known as cytochrome b5 isoform 1, is a member of membrane-bound cytochrome b5 family. It reduces ferric hemoglobin to ferrous hemoglobin, which is required for stearyl-CoA-desaturase activity. This protein acts as an electron carrier for several membrane bound oxygenases. Source: Recombinant protein corresponding to aa1-108 from human CYB5A, fused to His-Tag at C-terminal, expressed in Insect Cell. Molecular Weight: ~13.3kD (117aa) ~18-28KD (SDS-PAGE under reducing conditions) Enzyme Activity: Not determined. This product is recommended for use in applications that do not require a catalytically active form of the protein.
