(a) Organization of well characterized centromeres. Repeat sequences are denoted by arrows. The central blue box in the P1 centromere is recognized by IHF. The atypical P1 centromere also has two different repeats bound by ParB [11]. (b) Schematic diagram showing the general steps of plasmid segregation. Plasmids are represented as circles. The first step is formation of the partition complex by CBP binding to the centromere. This is followed by plasmid pairing (interacting circles). The NTPase molecules then interact with partition complexes and drive plasmid separation before cell division.
