Is sr-(Methionyl sh-Oligopeptide-75 sh-Polypeptide-1 Hexapeptide-40) vegetarian?

sr-(Methionyl sh-Oligopeptide-75 sh-Polypeptide-1 Hexapeptide-40) is a single-chain recombinant peptide produced by fermentation in E. coli. It is derived from a fusion gene combining sh-Oligopeptide-75, sh-Polypeptide-1, and Hexapeptide-40 sequences with an initiating methionine codon, yielding a 168-amino-acid fusion peptide that may contain disulfide bonds and/or glycosylation.

An ingredient is considered vegetarian if it avoids components derived from killing an animal.
