Methionyl sh-Polypeptide-47 is a single chain synthetic fusion peptide, produced by fermentation in Pichia pastoris. The starting gene is synthesized by the fusion of the gene from sh-Polypeptide-47 with the initiation code for methionine. The fusion peptide contains 456 amino acids which may contain disulfide bonds and/or glycosylation, and consists of the proper sequence of the 20 standard amino acids.
