Protease vs. Peptidase: Know the Difference
By Shumaila Saeed || Updated on December 25, 2023
Proteases break down proteins into smaller peptides or amino acids, while peptidases specifically cleave peptide bonds within peptides.
Key Differences
Proteases are enzymes that catalyze the breakdown of proteins into smaller peptides or amino acids. Peptidases, a subset of proteases, specifically cleave peptide bonds within peptides, further breaking them down.

Proteases act on a wide range of protein substrates, displaying broad specificity. Peptidases, on the other hand, show more specificity by targeting shorter peptide chains.

Both proteases and peptidases are classified based on their catalytic mechanism. Proteases include serine, threonine, cysteine, aspartic, and metalloproteases, while peptidases are often categorized within these classes but are defined by their peptide-specific action.
