Chromosome plasmid partitioning protein
R388 partition system The partition system of the plasmid R388 has been found within the stb operon. This operon is composed of three genes, stbA, stbB and stbC. StbA protein is a DNA-binding protein (identical to ParM) and is strictly required for the stability and intracellular positioning of plasmid R388 in E. … See more A plasmid partition system is a mechanism that ensures the stable inheritance of plasmids during bacterial cell division. Each plasmid has its independent replication system which controls the number of copies of … See more This system is also used by most bacteria for chromosome segregation. Type I partition systems are composed of an ATPase which … See more The type III partition system is the most recently discovered partition system. It is composed of tubulin-like GTPase termed TubZ, and the CBP is termed TubR. Amino-acid sequence identity can go down to 21% for TubZ proteins. The mechanism is … See more Plasmid copies are paired around a centromere-like site and then separated in the two daughter cells. Partition systems involve three elements, organized in an auto-regulated operon: • A centromere-like DNA site • Centromere binding proteins (CBP) See more This system is the best understood of the plasmid partition system. It is composed of an actin-like ATPAse, ParM, and a CBP called ParR.
