Amino acid sequence of ferredoxin from Arctium lappa

Ferredoxin from Arctium lappa consists of a single polypeptide chain of 97 residues, four of which are cysteine. These residues, which are in the active centre, are in identical positions to those of other ferredoxins. Overlap between residue positions 50/51 was not obtained, but amino acid composition of the two cyanogen bromide fragments which were overlapped corresponded with the amino acid composition of the total protein.
