Non-random segregation of sister chromosomes by Escherichia coli MukBEF axial cores

The Escherichia coli structural maintenance of chromosomes complex, MukBEF, forms axial cores to chromosomes that determine their spatio-temporal organization. Here, we show that axial cores direct chromosome arms to opposite poles and generate the translational symmetry between newly replicated sister chromosomes. MatP, a replication terminus (ter) binding protein, prevents chromosome rotation…
