WebRecent advances in saxitoxin research are discussed, including the molecular biology of toxin synthesis, new protein targets, association with metal-binding motifs and methods … WebStructure and synthesis. Saxitoxin dihydrochloride is an amorphous hygroscopic solid, but X-ray crystallography of crystalline derivatives enabled the structure of saxitoxin to be determined. Oxidation of saxitoxin generates a highly fluorescent purine derivative which has been utilized to detect its presence.
WebFeb 16, 2024 · The marine dinoflagellate Alexandrium is known to produce saxitoxins (STXs), causing paralytic shellfish poisoning (PSP). STX biosynthesis is catalyzed by eight enzymes encoded in their corresponding sxt core genes. SxtU encodes a short-chain dehydrogenase that participates in the last step of the STX synthesis; however, its … WebFeb 24, 2024 · Paralytic shellfish poisoning (PSP) is a human foodborne syndrome caused by the consumption of shellfish that accumulate paralytic shellfish toxins (PSTs, saxitoxin group). In PST-producing dinoflagellates such as Alexandrium spp., toxin synthesis is encoded in the nuclear genome via a gene cluster (sxt). Toxin production is supposedly …
