RT Bothrops mattogrossensis snake venom with toxicity against Leishmania and
RT tumor cells.";
RL Biomed. Res. Int. 2014:1-13(2014).
CC -!- FUNCTION: Snake venom phospholipase A2 that shows high myotoxic
CC activity, slight neutrophil activation (demonstrated by activation
CC induction of IL-1beta production), slight cytotoxicity against tumor
CC cell lines (T leukemia and breast adenocarcinoma), and slight
CC antiparasitic activity against promastigote forms of Leishmania
CC amazonensis. PLA2 catalyzes the calcium-dependent hydrolysis of the 2-
CC acyl groups in 3-sn-phosphoglycerides. {ECO:0000269|PubMed:24724078}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=a 1,2-diacyl-sn-glycero-3-phosphocholine + H2O = a 1-acyl-sn-
CC glycero-3-phosphocholine + a fatty acid + H(+); Xref=Rhea:RHEA:15801,
CC ChEBI:CHEBI:15377, ChEBI:CHEBI:15378, ChEBI:CHEBI:28868,
CC ChEBI:CHEBI:57643, ChEBI:CHEBI:58168; EC=3.1.1.4;
CC Evidence={ECO:0000269|PubMed:24724078};
CC -!- COFACTOR:
CC Name=Ca(2+); Xref=ChEBI:CHEBI:29108; Evidence={ECO:0000250};
CC Note=Binds 1 Ca(2+) ion. {ECO:0000250};
CC -!- SUBUNIT: Monomer. {ECO:0000269|PubMed:24724078}.
CC -!- SUBCELLULAR LOCATION: Secreted {ECO:0000269|PubMed:24724078}.
CC -!- TISSUE SPECIFICITY: Expressed by the venom gland.
CC {ECO:0000305|PubMed:24724078}.
CC -!- MASS SPECTROMETRY: Mass=13681; Method=MALDI;
CC Evidence={ECO:0000269|PubMed:24724078};
CC -!- MISCELLANEOUS: Does not induce platelet aggregation and does not
CC inhibit collagen or ADP-induced platelet aggregation.
CC {ECO:0000305|PubMed:24724078}.
CC -!- SIMILARITY: Belongs to the phospholipase A2 family. Group II subfamily.
CC K49 sub-subfamily. {ECO:0000305}.
