Enterokinase, also known as enteropeptidase, is a serine protease enzyme found in the small intestine of animals. Its main function is to activate trypsinogen, an inactive form of the digestive enzyme trypsin, by cleaving it to produce active trypsin.
Structure
Enterokinase is a membrane-bound enzyme located on the brush border of the duodenal and jejunal mucosa. It is made up of a catalytic subunit and a disulfide-linked heavy chain that is involved in substrate recognition. The enzyme is also highly specific, only activating trypsinogen and no other pancreatic zymogens.
Mechanism of Action
Upon reaching the small intestine, enterokinase cleaves the trypsinogen molecule at a specific site, releasing an N-terminal activation peptide and converting it into trypsin. This activated trypsin then goes on to activate other pancreatic zymogens, initiating the digestive process in the small intestine.
Role in Digestion
Enterokinase plays a crucial role in the digestion of proteins in the small intestine. Without its activation of trypsinogen, the body would not be able to efficiently break down and absorb proteins from the diet. This highlights the significance of enterokinase in the overall digestive process.
Enterokinase deficiency can lead to impaired protein digestion and absorption, causing malnutrition and digestive issues. Additionally, abnormal activation of trypsinogen can result in pancreatic damage and inflammation, leading to conditions like pancreatitis.
In conclusion, enterokinase is a vital enzyme involved in the activation of trypsinogen and the initiation of the digestive process in the small intestine. Its specificity and mechanism of action make it a key player in protein digestion and overall gastrointestinal health.
Enterokinase Examples
