Structural comparison of MtHigA3 bound to DNA and its homologues. (a) Cartoon representation of MtHigA3 bound to DNA (yellow), PvHigA bound to DNA (blue) and EcHipB bound to DNA (cyan). The C-terminus of the antitoxin which differs markedly in comparison is marked with a black dotted circle. Only the protein structures in these DNA–protein complexes are shown for clarity. (b) The superimposed cartoon represents the DNA structure of MtHigA3 bound to DNA (yellow), PvHigA bound to DNA (blue) and EcHipB bound to DNA (cyan). Only the DNA structures in these DNA–protein complexes are shown for clarity. (c) Structure of MtHigA3 bound to DNA, PvHigA bound to DNA and EcHipB bound to DNA. The antitoxins are presented as cartoon diagrams in surface view. Dimer angles between central stalks are indicated.
