Exopeptidases

Definition

Enzymes that break down proteins by sequentially removing amino acids from the terminal ends. While not exclusive to insect physiology, they play a significant role in the digestive systems of many insects by aiding in protein breakdown.

Etymology

From Greek 'exo-', meaning 'outside', and 'peptidases' referring to enzymes that break down peptides into amino acids.

Example

Exopeptidases are essential for protein digestion in the digestive tract of many insects.
