Species and Incompatibility Determination within the P1parFamily of Plasmid Partition Elements

Abstract: The P1par family of active plasmid partition systems consists of at least six members, broadly distributed in a variety of plasmid types and bacterial genera. Each encodes two Par proteins and contains a cis-acting parS site. Individual par systems can show distinct species specificities; the proteins from one type cannot function with the parS site of another. P1par-versus-P7par specificity resides within two hexamer BoxB repeats encoded by parS that contact the ParB protein near the carboxy terminus. Here, w… Show more

“…Although very similar, the P1 par, pMT1 par, and P7 par members each show unique partition specificities: the Par proteins of one species fail to function with the parS sites of the other two. These different par species are compatible with each other; they do not promote the incompatibility seen between pairs of plasmids that carry identical par elements (4).…”
