Schematic representation of the components of the ParMRC system. The operon for the ParMRC system consists of ParM and ParR regulated by the centromeric region of parC. ParM is an ATPase of actin fold, and forms double helical filaments. ParR is a repressor of ParM and ParR expression and also the adaptor between the DNA and the filaments. It links the parC DNA and the end of ParM filaments. Ten ParR dimers bind to the ten iterons (11-base pairs each) of parC and form the ParRC helical ring.
