Pseudomonas Exotoxin A (PE) is a potent toxin from Pseudomonas aeruginosa. This review details PE

Area of Science:

Microbiology
Molecular Biology
Evolutionary Biology

Background:

Pseudomonas Exotoxin A (PE) is a critical virulence factor of Pseudomonas aeruginosa.
PE's toxicity stems from its ability to impair and kill host cells.

Purpose of the Study:

To review current knowledge on PE intoxication pathways.
To highlight PE as an example of pathoadaptive evolution in bacterial toxins.

Main Methods:

Literature review of existing research on PE.
Analysis of evolutionary pressures shaping PE's structure and function.

Main Results:

Detailed description of PE's molecular mechanisms of host cell intoxication.
Evidence of PE's structural and functional optimization through evolution.

Keywords:

ADP ribosylation Pseudomonas Exotoxin A Pseudomonas aeruginosa cytotoxic pathways pathoadaptation virulence factor
