Chromosome partitioning protein

WebJul 7, 2008 · It is envisioned that the partitioning apparatus must consist of elements that are analogous to those involved in chromosome segregation in eukaryotic cells: a centromere binding protein, a mechanism to move the chromosomes towards the cell poles and, possibly, a mechanism of condensing the nascent chromosomes. The parABS system is a broadly conserved molecular mechanism for plasmid partitioning and chromosome segregation in bacteria. Originally identified as a genetic element required for faithful partitioning of low-copy-number plasmids, it consists of three components: the ParA ATPase, the ParB DNA-binding protein, and the cis-acting parS sequence. The parA and parB genes are typically found in the same operon, with parS elements located within or adjacent to this operon…

Partitioning has been hypothesized to be a necessary prerequisite for cytokinesis, which, in E. coli cells, requires a period of post-replication protein synthesis (Donachie and Begg, 1989). It is not known whether this period of protein synthesis supplies proteins for chromosome partitioning or cell division.
