ParS- independent … WebApr 24, 2007 · In a wide range of prokaryotes, the conserved ParA and ParB proteins play a role in the accurate partitioning of DNA. ParB family members recognize a specific site called parS, often present in multiple copies, and form higher-order complexes that facilitate the distribution of plasmids and/or chromosomes to daughter cells. Webplasmids and the chromosome relies on ParB proteins, which form large ParB–DNA complexes localized by a few or in rare cases by one parS site—a 16-bp sequence that specifically binds a ParB dimer (3). We first discuss how various types of protein– protein interactions in our model would affect the structure and scary game ideas

WebNov 2, 2024 · The ParAB S system plays an essential role in prokaryotic chromosome segregation. After loading at the parS site on the genome, ParB proteins rapidly redistribute to distances of ~15 kb away from the loading site. It has remained puzzling how this large-distance spreading can occur along DNA that is loaded with hundreds of proteins. Using … WebMay 31, 2024 · Bacterial centromeres–also called parS, are cis-acting DNA sequences which, together with the proteins ParA and ParB, are involved in the segregation of chromosomes and plasmids. The specific binding of ParB to parS nucleates the assembly of a large ParB/DNA complex from which ParA—the motor protein, segregates the …
