Biosynthesis of Saxitoxin in Marine Dinoflagellates: An Omics Perspective
Marine Drugs, 2020 Saxitoxin is an alkaloid neurotoxin originally isolated from the clam Saxidomus giganteus in 1957. This group of neurotoxins is produced by several species of freshwater cyanobacteria and marine dinoflagellates.
