CC -!- FUNCTION: Naturally present in the silkworm intestine and allows the
CC emerging moth to dissolve its cocoon.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=Preferential cleavage of bonds with hydrophobic residues in
CC 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 strain
CC presents in the gut of silkworms, is used as a food supplement because
CC it is reported to induces fibrinolytic, anti-inflammatory and anti-
CC edemic (prevents swelling and fluid retention) activity in a number of
CC tissues.
CC -!- SIMILARITY: Belongs to the peptidase M10B family. {ECO:0000305}.
CC -!- SEQUENCE CAUTION:
CC Sequence=CAA27738.1; Type=Frameshift; Evidence={ECO:0000305};
