RT metalloproteinase from the venom of Chinese snake (Gloydius blomhoffi
RT brevicaudus).";
RL Fukuoka Univ. Sci. Rep. 43:29-38(2013).
CC -!- FUNCTION: Non-hemorrhagic metalloproteinase that degrades fibrinogen.
CC The alpha chain (FGA) is rapidly degraded, the beta chain (FGB) is
CC degraded very slowly, while the gamma chain is left intact. Shows a
CC prefential cleavage at X-Leu bonds. Cleaves insulin B chain at '29-
CC His-|-Leu-30', '33-Ser-|-His-34', '38-Ala-|-Leu-39' and '40-Tyr-|-Leu-
CC 41' bonds. {ECO:0000269|Ref.1}.
CC -!- COFACTOR:
CC Name=Zn(2+); Xref=ChEBI:CHEBI:29105; Evidence={ECO:0000250};
CC Note=Binds 1 zinc ion per subunit. {ECO:0000250};
CC -!- ACTIVITY REGULATION: Its proteolytic activity is inhibited by EDTA,
CC TPEN, 1,10-phenanthroline, and some thiol compounds, but is enhanced by
CC alkaline earth metal ions (Mg2+, Ca2+, Sr2+, and Ba2+). Its activity is
CC not modulated by urea (4 M). {ECO:0000269|Ref.1}.
CC -!- BIOPHYSICOCHEMICAL PROPERTIES:
CC pH dependence:
CC Optimum pH is 9.5.;
CC -!- SUBUNIT: Monomer. {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Secreted.
CC -!- TISSUE SPECIFICITY: Expressed by the venom gland.
CC -!- PTM: Glycosylated (Ref.1). {ECO:0000269|Ref.1}.
CC -!- MISCELLANEOUS: Does not show hemorrhagic activity (Ref.1).
CC -!- MISCELLANEOUS: The disintegrin domain belongs to the long disintegrin
CC subfamily.
CC -!- SIMILARITY: Belongs to the venom metalloproteinase (M12B) family. P-III
CC subfamily. P-IIIa sub-subfamily. {ECO:0000305}.
