CC -!- FUNCTION: Thrombin-like enzyme that shows clotting activity upon human
CC plasma. Shows specific fibrinogenolytic activity for Aalpha chain
CC (FGA). Hydrolyzes fibrin, BAPNA and TAME, as well as chromogenic
CC artificial substrates of the blood coagulation cascasde: S-27654 for
CC factor X (F10), S-2302 for kallikrein (KLK), factor XIa (F11), and XIIa
CC (F12), and S-2266 for kallikrein and factor XIa (F11). Subcutaneous
CC injection into mice induces a mild edema. Intravenous and intramuscular
CC injection reduce plasma fibrinogen concentration and increase the
CC levels of fibrin(ogen) degradation products. Intramuscular injection
CC also promotes an increase in the expression of proMMP-9, but is unable
CC to activate it. {ECO:0000269|PubMed:17292935,
CC ECO:0000269|PubMed:17466550, ECO:0000269|PubMed:17996740}.
CC -!- ACTIVITY REGULATION: Inhibited by leupeptin, heparin, and 1.10-
CC phenantroline. {ECO:0000269|PubMed:17466550,
CC ECO:0000269|PubMed:17996740}.
CC -!- SUBUNIT: Monomer. {ECO:0000269|PubMed:17466550}.
CC -!- SUBCELLULAR LOCATION: Secreted.
CC -!- TISSUE SPECIFICITY: Expressed by the venom gland.
CC -!- PTM: N-glycosylated. Contains sialic acid residues. Deglycosylation
CC reduces in 50% the formation of fibrin clot.
CC {ECO:0000269|PubMed:17466550, ECO:0000269|PubMed:17996740}.
CC -!- MISCELLANEOUS: Negative results: does not show hemorrhagic and myotoxic
CC activities (PubMed:17466550), as well as activity on platelet
CC aggregation and plasmin (represented by the chromogenic substrate S-
CC 2251) (PubMed:17996740). {ECO:0000305|PubMed:17466550,
CC ECO:0000305|PubMed:17996740}.
CC -!- SIMILARITY: Belongs to the peptidase S1 family. Snake venom subfamily.
CC {ECO:0000255|PROSITE-ProRule:PRU00274}.
