1 Feedback Regulation of Cathepsin C by the Propeptide Dipeptides of Granzymes A and B. Dipeptides cathepsin C Homo sapiens
2 Granzymes A and B are activated by proteolytic removal of their N-terminal dipeptides by cathepsin C (dipeptidyl-peptidase I). Dipeptides cathepsin C Homo sapiens
3 Granzymes A and B are activated by proteolytic removal of their N-terminal dipeptides by cathepsin C (dipeptidyl-peptidase I). Dipeptides cathepsin C Homo sapiens
4 Cathepsin C is known to generate cytotoxic polymers from various dipeptides, however, in the case of the dipeptides Glu-Lys and Gly-Glu, cathepsin C was unable to polymerize them. Dipeptides cathepsin C Homo sapiens
5 Cathepsin C is known to generate cytotoxic polymers from various dipeptides, however, in the case of the dipeptides Glu-Lys and Gly-Glu, cathepsin C was unable to polymerize them. Dipeptides cathepsin C Homo sapiens
6 Cathepsin C is known to generate cytotoxic polymers from various dipeptides, however, in the case of the dipeptides Glu-Lys and Gly-Glu, cathepsin C was unable to polymerize them. Dipeptides cathepsin C Homo sapiens
7 Unexpectedly the dipeptides were found to be inhibitors of the transferase activity of cathepsin C (IC50 < 20 mM), and weak competitive inhibitors of the peptidase activity with Ki values in the millimolar range. Dipeptides cathepsin C Homo sapiens
8 This suggests that the dipeptides can play role in a feedback loop that controls transferase and proteolytic activities of cathepsin C in various biological processes. Dipeptides cathepsin C Homo sapiens
