General annotation (Comments)

Catalytic activity

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.

Sequence similarities

Belongs to the peptidase C1 family.
