Is sr-Sturgeon Polypeptide-4 vegetarian?

sr-Sturgeon Polypeptide-4 is a single-chain recombinant protein produced by fermentation in Pichia pastoris using a synthesized gene identical to that coding for extracellular superoxide dismutase [Cu-Zn] derived from the sturgeon Acipenser schrenckii. It is produced via biotechnology rather than from animal tissue.

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