CC -!- BIOPHYSICOCHEMICAL PROPERTIES:
CC Temperature dependence:
CC Loses its activity after heat treatment.
CC {ECO:0000269|PubMed:23159790};
CC -!- SUBCELLULAR LOCATION: Secreted {ECO:0000269|PubMed:23159790}.
CC -!- TISSUE SPECIFICITY: Expressed by the venom gland.
CC {ECO:0000305|PubMed:23159790}.
CC -!- PTM: Not glycosylated. {ECO:0000269|PubMed:23159790}.
CC -!- MASS SPECTROMETRY: Mass=33441.5; Method=MALDI;
CC Evidence={ECO:0000269|PubMed:23159790};
CC -!- ALLERGEN: Causes an allergic reaction in human. Binds to IgE.
CC {ECO:0000250|UniProtKB:A2VBC4}.
CC -!- TOXIC DOSE: 120 mg/kg body weight concentration is able to paralyze 67%
CC of the crickets (PD(67) is 120 mg/kg). {ECO:0000269|PubMed:23159790}.
CC -!- SIMILARITY: Belongs to the AB hydrolase superfamily. Lipase family.
CC {ECO:0000305}.
