Intralysosomal hydrolysis of glycyl-<scp>l</scp>-phenylalanine 2-naphthylamide

Glycyl-L-phenylalanine 2-naphthylamide (Gly-L-Phe-2-NNap), a cathepsin C substrate, induces an increase of the free and unsedimentable activities of this enzyme when incubated with a total mitochondrial fraction of rat liver. 1 mM-ZnSO4 considerably inhibits the cathepsin C total activity, measured ...
