For the Streptococcal superantigen SpeA, also referred to as exotoxin A, see Erythrogenic toxin.

The Pseudomonas exotoxin (orexotoxin A) is an exotoxin produced by Pseudomonas aeruginosa.[1] Vibrio cholerae produces a similar protein called the Cholix toxin (Q5EK40).[2]

It inhibits elongation factor-2. It does so by ADP-ribosylation of EF2 using NAD+. This then causes the elongation of polypeptides to cease. This mechanism is similar to that of diphtheria toxin.[3]

It has been investigated as a treatment for hepatitis B[4] and cancer.[5]
