Protease — Glossary

An enzyme that breaks down protein-based residue — the one matched to urine and biological soils.

Protease is the enzyme for protein. In pet odor, it targets the protein-based component of urine and other biological soils — breaking them into smaller compounds that release less odor.

It’s the enzyme most associated with urine-odor treatment, and a standard component of enzymatic pet-odor products.
