A PF08775 ParB ParB family Domain ParB is a component of the par system which mediates accurate DNA partition during cell division. It recognises A-box and B-box DNA motifs. ParB forms an asymmetric dimer with 2 extended helix-turn-helix (HTH) motifs that bind to A-boxes. The HTH motifs emanate from a beta sheet coiled coil DNA binding module [1]. Both DNA binding elements are free to rotate around a flexible linker, this enables them to bind to complex arrays of A- and B-box elements on adjacent DNA arms of the looped partition site [1].
