CC -!- FUNCTION: Naturally present in the silkworm intestine and allows CC the emerging moth to dissolve its cocoon. CC -!- CATALYTIC ACTIVITY: CC Reaction=Preferential cleavage of bonds with hydrophobic residues CC in P1'.; EC=3.4.24.40; CC -!- COFACTOR: CC Name=Ca(2+); Xref=ChEBI:CHEBI:29108; CC Note=Binds 7 Ca(2+) ions per subunit.; CC -!- COFACTOR: CC Name=Zn(2+); Xref=ChEBI:CHEBI:29105; CC Note=Binds 1 zinc ion per subunit.; CC -!- SUBCELLULAR LOCATION: Secreted. CC -!- MISCELLANEOUS: The Gly-rich repeats may be important in the CC extracellular secretion of this metalloprotease. CC -!- MISCELLANEOUS: In Japan this enzyme, isolated from a Serratia CC strain presents in the gut of silkworms, is used as a food CC supplement because it is reported to induces fibrinolytic, anti- CC inflammatory and anti-edemic (prevents swelling and fluid CC retention) activity in a number of tissues. CC -!- SIMILARITY: Belongs to the peptidase M10B family. {ECO:0000305}.
