RT   secreted by the parasitic trematode Fasciola hepatica.";
RL   Eur. J. Biochem. 223:91-98(1994).
CC   -!- FUNCTION: Thiol protease that assists the parasite in burrowing through
CC       the gut wall and liver of its mammalian host.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=Specificity close to that of papain. As compared to cathepsin
CC         B, cathepsin L exhibits higher activity toward protein substrates,
CC         but has little activity on Z-Arg-Arg-NHMec, and no peptidyl-
CC         dipeptidase activity.; EC=3.4.22.15;
CC   -!- SUBUNIT: Dimer of a heavy and a light chain linked by disulfide bonds.
CC   -!- SUBCELLULAR LOCATION: Lysosome.
CC   -!- SIMILARITY: Belongs to the peptidase C1 family. {ECO:0000255|PROSITE-
CC       ProRule:PRU10088, ECO:0000255|PROSITE-ProRule:PRU10089,
