the use of cytosol proteins as substrates has allowed the detection of two new lysosomal cysteine proteinases from rat liver : the endoaminopeptidase cathepsin h and cathepsin l , which splits almost no synthetic substrates but has a more than 10-fold higher specific activity with proteins as substrates than other mammalian cysteine proteinases .
