Family relationships



ToxN acts as a toxin, it is part of a type III toxin-antitoxin system. It acts as a ribosome independent endoribonuclease. It interacts with, and is inhibited by, the RNA antitoxin, ToxI [PMID: 19124776,PMID: 21240270]. Three ToxN monomers bind to three ToxI monomers to create a trimeric ToxN-ToxI complex [PMID: 21240270].
