CTRC cleavage of the trypsinogen activation peptide stimulates. ( see table 1), a residue after which trypsin or enteropeptidase cannot cleave.
Trypsinogen is the inactive precursor of trypsin ( PRSS1, human cationic trypsinogen), which can cleave proteins and peptides after lysine and arginine residues and is activated by the membrane- bound enteropeptidase via cleavage of the N- terminal activation peptide located on the trypsinogen surface. Cathepsin B cleavage of the trypsinogen activation peptide Cathepsin B cleavage of the trypsinogen activation peptide. Additional trypsinogen activation peptide sequences from the most vertebrate- like invertebrates such as hagfish and Amphioxus and other species of Chondrichthyes may help to.

Peptide bonds are formed when the amine group of one amino acid binds with the. Trypsinogen activation peptide ( TAP) is the amino- terminal peptide of 5 or 8 amino acids released during activation of trypsinogen. The tool accepts both DNA and RNA sequences. The studies, which have demonstrated that cathepsin B can activate trypsinogen in vitro, further support this theory ( 25, 29) and it seems that in the absence of cathepsin B, less than 1 % of the trypsinogen peptide is hydrolyzed but after incubation with cathepsin B for 30 min at pH 5, 96% of trypsinogen peptide was hydrolyzed ( 29.

The activation peptide of mammalian trypsinogens contains a highly conserved tetra- aspartate sequence ( D19- D20- D21- D22) preceding the K23- I24 scissile.
With the initiator methionine of the primary translation product, according to the. Discrimination of three mutational events that result in a disruption of the. Mutation A16V, which changes the first amino acid in the trypsinogen activation peptide, accelerates CTRC- mediated processing, and carriers of this mutation are at risk of developing chronic pancreatitis ( 8). Although activation of trypsinogen to trypsin requires proteolysis of the second site, cleavage after the first Lys may modify the efficiency of the second cleavage. Finally, processing of the trypsinogen activation peptide at Phe- 18 by CTRC. Sequence identified 18 different exact matches.Activation of trypsinogen. Octapeptide sequence, ( Glu) 5.
