protease

Peptide bond breaker

A protease is an enzyme that breaks down proteins by cleaving the bonds between amino acids.

Proteases occur throughout nature and serve vital roles in digestion, immune response, and cellular regulation.

Digestive proteases like pepsin and trypsin break down dietary protein in the gut.
