Crosstalk Regulation Between Bacterial Chromosome Replication and Chromosome Partitioning [PDF]
Despite much effort, the bacterial cell cycle has proved difficult to study and understand. Bacteria do not conform to the standard eukaryotic model of sequential cell-cycle phases. Instead, for example, bacteria overlap their phases of chromosome replication and chromosome partitioning.

A novel nucleoid-associated protein coordinates chromosome replication and chromosome partition. [PDF]
We searched for regulators of chromosome replication in the cell cycle model Caulobacter crescentus and found a novel DNA-binding protein (GapR) that selectively aids the initiation of chromosome replication and the initial steps of chromosome partitioning. The protein binds the chromosome origin of replication (Cori) and has higher-affinity binding to

Plasmid and chromosome partitioning: surprises from phylogeny [PDF]
Plasmids encode partitioning genes (par) that are required for faithful plasmid segregation at cell division. Initially, par loci were identified on plasmids, but more recently they were also found on bacterial chromosomes. We present here a phylogenetic analysis of par loci from plasmids and chromosomes from prokaryotic organisms.

Psammaplysin F: A unique inhibitor of bacterial chromosomal partitioning
Described is the antibiotic activity of a marine natural product. Psammaplysin F (1) inhibited the growth of four Gram-positive strains by >80% at 50μM, and the amine at position C-20 is responsible for the observed antibacterial activity. When tested against two strains of methicillin resistant Staphylococcus aureus (MRSA), the minimum inhibitory ...

Vibrio cholerae Chromosome Partitioning without Polar Anchoring by HubP [PDF]
Partition systems are widespread among bacterial chromosomes. They are composed of two effectors, ParA and ParB, and cis acting sites, parS, located close to the replication origin of the chromosome (oriC). ParABS participate in chromosome segregation, at least in part because they serve to properly position sister copies of oriC.

Abortive recombination in Escherichia coli ruv mutants blocks chromosome partitioning [PDF]
Background:All the ruvA, ruvB and ruvC mutants of Escherichia coli are sensitive to treatments that damage DNA, and are mildly defective in homologous recombination. It has been reported that the ruv mutants form nonseptate, multinuclear filaments after low doses of UV irradiation, dependent on the sfiA gene product.

Partition of distinct chromosomal regions: negotiable border and fixed border [PDF]
Chromosomes are partitioned into distinct functional regions. For example, heterochromatin regions consist of condensed chromatin and contain few transcriptionally active genes, whereas euchromatin regions are less condensed and majority of active genes reside in the euchromatin regions.

Characterization of chromosomal and megaplasmid partitioning loci in Thermus thermophilus HB27 [PDF]
In low-copy-number plasmids, the partitioning loci (par) act to ensure proper plasmid segregation and copy number maintenance in the daughter cells. In many bacterial species, par gene homologues are encoded on the chromosome, but their function is much less understood.

Postseptational chromosome partitioning in bacteria. [PDF]
Mutations in the spoIIIE gene prevent proper partitioning of one chromosome into the developing prespore during sporulation but have no overt effect on partitioning in vegetatively dividing cells. However, the expression of spoIIIE in vegetative cells and the occurrence of genes closely related to spoIIIE in a range of nonsporulating eubacteria ...
