Activation of trypsinogen

Trypsin, which is itself another proteolytic enzyme, activates the precursor zymogens (such as chymotrypsinogen) Trypsinogen is activated by the enzyme enterokinase, which is embedded in the intestinal mucosa. Once trypsin is formed it activates chymotrypsinogen, as well Trypsinogen is activated into trypsin by an enzyme .X. play. 278685308.

Subcellular fractionation and analysis of pancreatic homogenate shortly after the induction of pancreatitis have provided much insight about the location of trypsinogen activation. Activation of human trypsinogens by enteropeptidase, trypsinogen or trypsin occurs through hydrolyzing the peptide bond after Lys23 (Figure 576.2).

', Journal of Leukocyte Activation of trypsinogen. Trypsinogen is activated by enteropeptidase (also known as enterokinase). Enteropeptidase is produced by the mucosa of duodenum and it cleaves the peptide bond of trypsinogen after residue 15, which is a lysine. The N-terminal peptide is discarded, and a slight rearrangement of the folded protein occurs.

However, activation of trypsinogen within the acinar cell plays a key role in the pathogenesis of acute pancreatitis, because conversion of trypsinogen triggers a pancreatic enzyme cascade that activates the remaining zymogens, resulting in autodigestion of the surrounding tissue (Rinderknecht, 1986). Trypsinogen activation peptide (TAP) is a cleavage product of trypsinogen which is released into systemic circulation with zymogen granule activation. Because of its low molecular weight, TAP is rapidly excreted in urine and is easily detected in both urine and serum.

Activation of trypsinogen by enterokinase in the duodenum [1] is the initial step in the normal activation of pancreatic digestive enzymes.

While it is clear that there is intra-acinar activation of trypsin, the exact intracellular location where trypsin is activated is a hotly debated area in pancreatitis. Subcellular fractionation and analysis of pancreatic homogenate shortly after the induction of pancreatitis have provided much insight about the location of trypsinogen activation.

An acidic environment also is important for trypsinogen activation (20 –22).
