A Polymeric Protein Anchors the Chromosomal Origin/ParB Complex at a Bacterial Cell Pole

Abstract

Bacterial replication origins move towards opposite ends of the cell during DNA segregation. We have identified a proline-rich polar protein, PopZ, required to anchor the separated Caulobacter crescentus chromosome origins at the cell poles, a function that is essential for maintaining chromosome organization and normal cell division. PopZ interacts… (More)
