== Function ==

Exotoxins (ET) are toxins which are secreted by Gram-positive and Gram-negative bacteria<ref>PMID:17675409</ref>. ETs are heat labile.  They are highly toxic and fatal in μg quantities.  ETs bind to specific receptors and have no enzymatic activity.

== Relevance ==

Exotoxins are involved in tetanus, diphtheria and botulism.
