General annotation (Comments)

Function

Has insecticidal activity against the locust M.palpalis. When administered orally to locusts at a low dose it causes them to lie on their sides exhibiting sporadic limb movements and muscular twitching, followed by full recovery. When administered at higher doses the same symptoms are observed, followed by death. Ref.2

Catalytic activity

Preferential cleavage of bonds with hydrophobic residues in P1'. Ref.2

Cofactor

Binds 7 calcium ions per subunit. Ref.2

Binds 1 zinc ion per subunit. Ref.2

Subcellular location

Secreted.

Miscellaneous

The Gly-rich repeats may be important in the extracellular secretion of this metalloprotease.

Sequence similarities

Belongs to the peptidase M10B family.

Contains 2 hemolysin-type calcium-binding repeats.
