RT metalloprotease from the Brazilian scorpion Tityus serrulatus.";
RL J. Biol. Chem. 285:7405-7416(2010).
CC -!- FUNCTION: Acts as a metalloprotease. Penetrates intact tissue and
CC specifically cleaves the vesicle-associated membrane protein 2 (VAMP2)
CC (part of the SNARE complex) involved in pancreatic secretion, thus
CC disrupting the normal vesicular traffic. {ECO:0000269|PubMed:20026600}.
CC -!- COFACTOR:
CC Name=Zn(2+); Xref=ChEBI:CHEBI:29105;
CC Evidence={ECO:0000250|UniProtKB:Q3ZD74};
CC Note=Binds 1 zinc ion per subunit. {ECO:0000250|UniProtKB:Q3ZD74};
CC -!- ACTIVITY REGULATION: Inhibited by EDTA. {ECO:0000269|PubMed:20026600}.
CC -!- SUBCELLULAR LOCATION: Secreted {ECO:0000269|PubMed:20026600}.
CC -!- TISSUE SPECIFICITY: Expressed by the venom gland.
CC {ECO:0000269|PubMed:20026600}.
CC -!- PTM: Contains 4 disulfide bonds. {ECO:0000305|PubMed:25091350}.
CC -!- MASS SPECTROMETRY: Mass=25500; Mass_error=100; Method=SELDI;
CC Evidence={ECO:0000269|PubMed:20026600};
CC -!- SIMILARITY: Belongs to the venom metalloproteinase (M12B) family.
