This is an alpha helix domain found in the N-terminal region of antitoxin RelB. RelE-RelB (RelBE) is a toxin-antitoxin (TA) protein complex. It is suggested that the toxic action of RelE is counteracted by antitoxin RelB, which wraps around RelE, blocks its active site and prevents sterically the binding to the ribosomal A-site.The long N-terminal alpha-helix of the tightly bound antitoxin RelB covers the presumed active site of the toxin RelE that is formed by a central beta-sheet [1].
ParE toxin of type II toxin-antitoxin system, parDE
ParE is the toxin family of a type II toxin-antitoxin family. It is toxic towards DNA gyrase, but is neutralised by the antitoxin ParD. The family also encompasses RelE/ParE described in [2].
