Participation of the bacterial membrane in DNA replication and chromosome partition
Trends in Cell Biology, 1993The concept that the bacterial membrane plays an active role in the regulation of DNA replication and in segregation, or 'partition', of the bacterial chromosome at cell division was proposed in 1963. Membrane participation offered a relatively simple way to coordinate replication and partition.

Crystal structure of the chromosome partition protein MukE homodimer
Biochemical and Biophysical Research Communications, 2022The SMC (structural maintenance of chromosomes) proteins are known to be involved in chromosome pairing or aggregation and play an important role in cell cycle and division. Different from SMC-ScpAB complex maintaining chromosome structure in most bacteria, the MukB-MukE-MukF complex is responsible for chromosome condensation in E.

Mutants defective in chromosome partitioning in E. coli
Research in Microbiology, 1991Recent experimental results suggest that replicated daughter chromosomes (nucleoids) in Escherichia coli move non-progressively and abruptly at an early stage of the D (division) period from midcell toward the cell quarter positions, which will become the centres of the daughter cells. The chromosome positioning at the quarter positions was found to be

Chromosome partition in Escherichia coli requires postreplication protein synthesis
Journal of Bacteriology, 1989 After inhibition of protein synthesis, the number of nuclear bodies (nucleoids) visible in cells of Escherichia coli B/rA corresponded closely to the number of completely replicated chromosomes. We calculated that nucleoid partition follows almost immediately after replication forks reach the chromosome terminus.

Chromosome segregation in Archaea mediated by a hybrid DNA partition machine [PDF]
Proceedings of the National Academy of Sciences of the United States of America, 2012 Eukarya and, more recently, some bacteria have been shown to rely on a cytoskeleton-based apparatus to drive chromosome segregation. In contrast, the factors and mechanisms underpinning this fundamental process are underexplored in archaea, the third domain of life. Here we establish that the archaeon Sulfolobus

RecA protein of Escherichia coli and chromosome partitioning
Molecular Microbiology, 1992Summary Escherichia coli cells deficient in RecA protein frequently contain an abnormal number of chromosomes after completion of ongoing rounds of DNA replication. This suggests that RecA protein may be required for correct timing of initiation of DNA replication; however, we show here that initiation of DNA replication is properly timed in recA ...

Partitioning of the Escherichia coli chromosome:Superhelicity and condensation
Biochimie, 2001Segregation in Escherichia coli, the process of separating the replicated chromosomes into daughter progeny cells, seems to start long before the duplication of the genome reaches completion. Soon after initiation in mid-cell region, the daughter oriCs rapidly move apart to fixed positions inside the cell (quarter length positions from each pole) and ...
