the deduced protein can be divided into four domains , based on homologies with other cysteine proteinases : the pre- , pro- and central regions show considerable homology to the cathepsin l class of mammalian enzymes , whilst the long c-terminal extension distinguishes the trypanosome enzyme from all mammalian cysteine proteinases reported .
