oligopeptidase

An oligopeptidase is a type of proteolytic enzyme that specifically breaks down peptides into smaller fragments or amino acids. Proteolytic enzymes, found in a wide range of organisms including bacteria, plants, and animals, are crucial for processes like digestion and cellular maintenance.12

These enzymes work by cleaving the long chains of proteins. They are broadly categorized into exopeptidases, which act on the ends of protein chains, and endopeptidases, which target internal sites. Oligopeptidases fall under the category of enzymes that act on peptides.1

In digestion, proteolytic enzymes like pepsin in the stomach and trypsin and chymotrypsin from the pancreas in the small intestine break down food proteins into amino acids for absorption.12
