CC -!- FUNCTION: Hydrolyzes nucleotides into nucleosides (By similarity).
CC Snake venom 5'-nucleotidases are widely distributed among venomous
CC snake taxa, but there is a lack of information about their biological
CC activities. They have been shown to inhibit platelet aggregation. This
CC effect may be due to the liberation of inhibitory AMP or adenosine by
CC its action on ADP released upon initiation of aggregation. Venom 5'-
CC nucleotidases are also known to synergistically act in vivo with other
CC toxins like ADPases, phospholipases, and disintegrins to exert a more
CC pronounced anti-coagulant effect. {ECO:0000250|UniProtKB:P0DJJ5,
CC ECO:0000305|PubMed:20186872}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=a ribonucleoside 5'-phosphate + H2O = a ribonucleoside +
CC phosphate; Xref=Rhea:RHEA:12484, ChEBI:CHEBI:15377,
CC ChEBI:CHEBI:18254, ChEBI:CHEBI:43474, ChEBI:CHEBI:58043; EC=3.1.3.5;
CC -!- COFACTOR:
CC Name=Zn(2+); Xref=ChEBI:CHEBI:29105; Evidence={ECO:0000250};
CC -!- SUBCELLULAR LOCATION: Membrane {ECO:0000250|UniProtKB:P0DJJ5}; Lipid-
CC anchor, GPI-anchor {ECO:0000250|UniProtKB:P21589}.
CC -!- TISSUE SPECIFICITY: Expressed by the venom gland.
CC -!- PTM: Venom 5'-nucleotidases (or a part thereof) may be released into
CC the venom via exosome-like vesicles. They may be attached via a GPI
CC anchor to the membrane of these vesicles. Soluble forms of 5'-
CC nucleotidase might be released by cleavage of the ectodomain in the
CC exosome-like vesicles or venom gland cells.
CC -!- SIMILARITY: Belongs to the 5'-nucleotidase family. {ECO:0000305}.
