FAQ
Frequently Asked Questions
Yes, the subtilisin used in detergents is engineered and formulated to be safe, effective, and non-irritating in its final product form.
No, it has specificity. It cleaves peptide bonds adjacent to certain amino acids, so its activity depends on the protein's sequence and structure.
It is derived from the Latin name of the bacterium that produces it, Bacillus subtilis.
Primarily as a research tool in laboratories for protein analysis. It is not a common therapeutic drug itself.
