Nicotiana Benthamiana r-(s-Hordeum Vulgare Oligopeptide-1 sh-Polypeptide-166) is a single chain recombinant peptide produced by Nicotiana benthamiana after transformation with either a transient expression system or transgenesis (stable insertion of a copy of the synthetic gene into its DNA). The starting gene is synthesized by the fusion of the genes from s-Hordeum Vulgare Oligopeptide-1 and sh-Polypeptide-166. The peptide contains a maximum of 1389 amino acids which may contain disulfide bonds and/or glycosylation. The fusion peptide consists of the proper sequence of the 20 standard amino acids.
