-
up to 260% activation of cythepsin E, KD value about 300 nM. Treatment of HeLa cells with cathepsin E and peptide results in decrease in cell viability, with a 1.5- and 3-fold increase in the level of apoptosis in comparison to cells treated with cathepsin E alone
-
the catalytically inactive proenzyme procathepsin E is rapidly converted to the active enzyme cathepsin E after brief treatment at pH 4 by autoproteolytic cleavage at Met36-Ile37 and Phe39-Thr40 to form two mature isozymic forms
