Enzyme Information

3.4.22.15
Cathepsin L.
based on mapping to UniProt P07711
Specificity close to that of papain. As compared to cathepsin B, cathepsin L exhibits higher activity toward protein substrates, but has little activity on Z-Arg-Arg-NHMec, and no peptidyl-dipeptidase activity.
-!- A lysosomal enzyme that is readily inhibited by the diazomethane inhibitor Z-Phe-Phe-CHN(2) or the epoxide inhibitor E-64. -!- Belongs to peptidase family C1.
