FitA-like ribbon-helix-helix domain-containing protein
This domain is found in Antitoxin FitA from Neisseria gonorrhoeae and similar bacterial sequences. FitA is the antitoxin component of a type II toxin-antitoxin (TA) system. It binds DNA through its ribbon-helix-helix motif (this entry) [1]. Paper describing PDB structure 2bsq. [1]. 16982615. Structure of FitAB from Neisseria gonorrhoeae bound to DNA reveals a tetramer of toxin-antitoxin heterodimers containing pin domains and ribbon-helix-helix motifs.
