saxitoxin[¦sak·sə¦täk·sən] (biochemistry) A nonprotein toxin produced by the dinoflagellate Gonyaulax catenella. saxitoxin
saxitoxin [sak´sĭ-tok″sin] a powerful heat-stable low molecular weight neurotoxin synthesized and secreted by certain dinoflagellates, such as species of Gonyaulax, which accumulates in the tissue of bivalve mollusks feeding on the dinoflagellates; it may cause a severe toxic reaction called shellfish poisoning in those who ingest contaminated mollusks.sax·i·tox·in (sak'si-tok'sin), A potent neurotoxin found in shellfish, such as the mussel or the clam (and sometimes the pufferfish, Sphoerides nephelus), produced by the dinoflagellate Gonyaulax catenella, which is ingested by the shellfish; the cause of cases of poisoning from eating the California sea mussel (Mytilus californianus), scallop, and the Alaskan butterclam (Saxidomus giganteus).saxitoxin (săk′sĭ-tŏk′sĭn)n. A potent neurotoxin produced by certain dinoflagellates that accumulates in shellfish feeding on these organisms and consequently causes food poisoning in humans who eat the shellfish.A potent paralyzing neurotoxin first isolated from the Alaskan clam—Saxidomus giganteus—which binds to the cell membrane’s Na+ channel, blocking depolarisation at the neuromuscular junction, and increasing permeability for Na+; the toxin is heat-stable, water-soluble and rapidly absorbed from the GI tract; as few as 6 contaminated clams may be fatalsax·i·tox·in (sak'si-tok'sin) A potent neurotoxin found in shellfish, such as the mussel or the clam, produced by the dinoflagellate Gonyaulax catenella, which is ingested by the shellfish; the cause of poisoning due to eating California sea mussels, scallops, and Alaskan butterclams.
