WebMay 1, 2024 · Partitioning the replicated genetic material is a crucial process in the cell cycle program of any life form. In bacteria, many plasmids utilize cytoskeletal proteins that include ParM and TubZ ... WebJan 1, 2014 · The partition proteins belong to the parAB superfamily, as for most chromids, which is widely distributed on both chromosomal and plasmid replicons. However, chromid- and plasmid-encoded Par proteins tend to group in phylogenetic analyses and separate from those encoded by the primary chromosome (Dubarry et al. 2006 ).
WebJan 22, 1999 · The partition module of plasmid P1 is typical and consists of a centromere site, parS, and genes that encode proteins ParA and ParB. We show that ParB can silence genes flanking parS (to which ParB binds), apparently by polymerizing along the DNA from a nucleation site at parS. WebThe ParABS system mediates chromosome segregation and plas- mid partitioning in many bacteria. As part of the partitioning mechanism, ParB proteins form a …
