The recombinant protein has gelatinase activity. In vivo, injection of this recombinant into fifth instar L.oleracea (host) larvae results in partial insect mortality associated with the molt to sixth instar, with surviving insects showing retarded development and growth (By similarity). Binds 1 zinc ion per subunit. The gelatinase activity is inhibited by EDTA. Monomer. Expressed by the venom gland. The N-terminal section (alone) shows no toxic effect when injected into the host. This section may function in stabilizing the catalytic part of the protein, or in directing it to specific target sites of action (By similarity). In the C-terminal section; belongs to the venom metalloproteinase (M12B) family.
