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.
