Tetrodotoxin Biosynthesis

Tetrodotoxin biosynthesis is the process by which certain marine bacteria and some animals produce a potent toxin that blocks nerve signals. This toxin is generated through a series of complex chemical reactions within these organisms, involving specialized enzymes that build and modify the toxin’s molecular structure. The bacteria often produce tetrodotoxin, which then accumulates in animals like pufferfish, octopuses, and others, either directly or through their diet. This natural production helps these animals defend against predators by effectively numbing or paralyzing potential threats.
