Is Methionyl sh-Polypeptide-3 vegetarian?

Methionyl sh-Polypeptide-3 is a single-chain synthetic peptide produced by fermentation in E. coli. The starting gene is synthesized by adding the initiation codon for methionine to the gene for sh-Polypeptide-3, yielding a 164-amino-acid peptide that may contain disulfide bonds and/or glycosylation.

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