Accessory factors determine the order of strand exchange in Xer recombination at psi.

The EMBO journal - 15 Jul 2002

Bregu Migena, Sherratt David J, Colloms Sean D

Abstract excerpt

Xer site-specific recombination in Escherichia coli converts plasmid multimers to monomers, thereby ensuring their correct segregation at cell division. Xer recombination at the psi site of plasmid pSC101 is preferentially intramolecular, giving products of a single topology. This intramolecular selectivity is imposed by accessory proteins, which bind at psi accessory sequences and activate Xer recombination at...
