Chlamydomonas r-(Oligopeptide-91 sh-Polypeptide-11 sh-Polypeptide-1 sh-Polypeptide-11) is a single chain recombinant peptide, produced by fermentation in the alga, Chlamydomonas reinhardtii. The starting gene is synthesized by the fusion of the genes encoding for Oligopeptide-91, sh-Polypeptide-11 and sh-Polypeptide-1. The fusion peptide contains 156 amino acids which may contain disulfide bonds and/or glycosylation, and consists of the proper sequence of the 20 standard amino acids.
