Microbiol. Biotechnol. 99:9971-9986(2015). CC -!- FUNCTION: Thrombin-like snake venom serine protease. Has coagulant CC activity, releasing fibrinopeptide A and B in the conversion of CC fibrinogen to fibrin. Also hydrolyzes N-p-toluensulfonyl arginine ester CC (TAME) and chromogenic artificial substrates of the blood coagulation CC cascade: S-2222 for factor Xa, S-2302 for kallikrein and S-2238 for CC thrombin. {ECO:0000269|PubMed:26227411}. CC -!- ACTIVITY REGULATION: Inhibited by Cu(2+) and, to a lesser extent, by CC Zn(2+) and Ba(2+). Not inhibited by Ca(2+) and Mg(2+). CC {ECO:0000269|PubMed:26227411}. CC -!- BIOPHYSICOCHEMICAL PROPERTIES: CC Kinetic parameters: CC KM=1.43 mM for TAME {ECO:0000269|PubMed:26227411}; CC Vmax=0.06 mmol/min/ug enzyme towards TAME CC {ECO:0000269|PubMed:26227411}; CC pH dependence: CC Activity is stable from pH 3.5 and 10.5. CC {ECO:0000269|PubMed:26227411}; CC Temperature dependence: CC Thermostable. Activity is stable after incubation at 100 degrees CC Celsius for 30 min. {ECO:0000269|PubMed:26227411}; CC -!- SUBUNIT: Monomer. {ECO:0000305|PubMed:26227411}. CC -!- SUBCELLULAR LOCATION: Secreted {ECO:0000269|PubMed:26227411}. CC -!- TISSUE SPECIFICITY: Expressed by the venom gland. CC {ECO:0000305|PubMed:26227411}. CC -!- MASS SPECTROMETRY: Mass=29474; Method=Electrospray; CC Evidence={ECO:0000269|PubMed:26227411}; CC -!- SIMILARITY: Belongs to the peptidase S1 family. Snake venom subfamily. CC {ECO:0000255}.
