The RTX toxin family is a group of exotoxins produced by gram-negative bacteria. All RTX toxins share a common gene organization and structural appearance. Gram-negative bacteria secrete the toxins into the extracellular space using the type I secretion system. RTX is an abbreviation of "repeats in toxin," which is a reference to the repeated peptide sequences found within the toxins. RTX toxins are divided into hemolysins and leukotoxins.
