RT   (Vespapase, Ves a 1) from Thai banded tiger wasp (Vespa affinis) venom.";
RL   Toxicon 61:151-164(2013).
CC   -!- FUNCTION: Catalyzes the hydrolysis of phosphatidylcholine with
CC       phospholipase A1 (EC 3.1.1.32) activity (PubMed:23159790). Shows
CC       hemolytic activity (By similarity). Shows a phospholipase A1 enzymatic
CC       activity of 3.6 U/ml (PubMed:23159790). In vivo, a mixture of this
CC       protein and Ves a 1.02 is able to paralyze crickets (PubMed:23159790).
CC       {ECO:0000250|UniProtKB:P0DMB7, ECO:0000269|PubMed:23159790}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=a 1,2-diacyl-sn-glycero-3-phosphocholine + H2O = a 2-acyl-sn-
CC         glycero-3-phosphocholine + a fatty acid + H(+); Xref=Rhea:RHEA:18689,

CC         Evidence={ECO:0000269|PubMed:23159790};
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: 60 mg/kg body weight of a mixture of this protein and Ves a
CC       1.02 is able to paralyze 33% of the crickets.
CC       {ECO:0000269|PubMed:23159790}.
CC   -!- SIMILARITY: Belongs to the AB hydrolase superfamily. Lipase family.
CC       {ECO:0000305}.
