Pentapeptide-60 s-Methanocaldococcus Jannaschii Heptapeptide-1 is a single chain fusion peptide produced synthetically. The starting gene is synthesized by the fusion of the gene from s-Methanocaldococcus Jannaschii Heptapeptide-1 and Pentapeptide-60, The fusion peptide contains 12 amino acids which may contain disulfide bonds and/or glycosylation, and consists of the proper sequence of the 20 amino acids.
