This entry represents the N-terminal domain of the antitoxin component Xre of a type II toxin-antitoxin (TA) system, which is the helix-turn-helix (HTH) DNA binding domain, structurally similar to the Cro repressor, therefore, also referred to as HTH/Cro-like DNA-binding domain [2]. This domain is also found in other antitoxin components, associated with a C-terminal toxin-binding domain Pfam:PF09722 [1,2].	Domain

This entry represents the C-terminal domain of antitoxin components of a type II toxin-antitoxin (TA) system, including Xre from Pseudomonas putida, MbcA from Mycobacterium sp. and ParS from Sphingobium sp. [1,2,3,4]. This domain interacts with the toxin component and sterically blocks its active site, neutralising its effect [2,3]. These antitoxins also have a HTH domain at the N-terminal.	Domain
