The primary structure of bovine adrenodoxin

The amino acid sequence of bovine adrenodoxin has been detemined except for the assignment of a few acid or amide groups. The protein contains 118 amino acids in the form of a single polypeptide chain. The five cysteine residues, most of which are involved in iron binding, are located at position 46, 52, 55, 95 and 98. The molecular weight of the protein from the amino acid content and the labile sulfide and the iron content is about 13,094.
