sr-(Caudoviricetes Polypeptide-1 Dipeptide-81 Cutibacterium Acnes Polypeptide-1 Pentapeptide-124 Dipeptide-19 Hexapeptide-40) is a single chain recombinant peptide produced by fermentation in E. coli. The starting gene is synthesized by the fusion of the gene from r-Caudoviricetes Polypeptide-1, Dipeptide-81, r-Cutibacterium Acnes Polypeptide-1, Pentapeptide-124, Dipeptide-19, and Hexapeptide-40. The fusion peptide contains 279 amino acids which may contain disulfide bonds and/or glycosylation, and consists of the proper sequence of the 20 standard amino acids.
