The relaxase of the Rhizobium etli symbiotic plasmid shows nic site cis-acting preference.
Genetic and biochemical characterization of TraA, the relaxase of symbiotic plasmid pRetCFN42d from Rhizobium etli, is described. After purifying the relaxase domain (N265TraA), we demonstrated nic binding and cleavage activity in vitro and thus characterized for the first time the nick site (nic) of a plasmid in the family Rhizobiaceae. We studied the range of N265TraA relaxase specificity in ...
متن کاملStructural elements required for replication and incompatibility of the Rhizobium etli symbiotic plasmid.
The symbiotic plasmid of Rhizobium etli CE3 belongs to the RepABC family of plasmid replicons. This family is characterized by the presence of three conserved genes, repA, repB, and repC, encoded by the same DNA strand. A long intergenic sequence (igs) between repB and repC is also conserved in all members of the plasmid family. In this paper we demonstrate that (i) the repABC genes are organiz...
