BrnA antitoxin of type II toxin-antitoxin system; BrnA is family of antitoxins that neutralizes the toxin BrnT, pfam04365. It consists of 3 alpha-helices and a C-terminal ribbon-helix-helix DNA binding domain. As in other toxin-antitoxin systems, BrnA negatively autoregulates the brnTA operon and has higher affinity for the DNA operator when complexed with BrnT. It dimerizes with two molecules of its toxin BrnT.
