RT "Molecular cloning and primary sequence of a cysteine protease expressed by
RT Haemonchus contortus adult worms.";
RL Mol. Biochem. Parasitol. 41:25-34(1990).
CC -!- FUNCTION: Expression of the protease correlates with blood-feeding and
CC suggests a role for the protease in blood digestion.
CC -!- DEVELOPMENTAL STAGE: At low level in the third and fourth-stage larvae,
CC and abundant in adult worms.
CC -!- SIMILARITY: Belongs to the peptidase C1 family. {ECO:0000255|PROSITE-
