Molecular and functional analysis fo pTAV320, a repABC-type replicon of the Paracoccus versutus composite plasmid pTAV1

Research was conducted to characterize the second replicator region of pTAV1 which is part of the mini-replicon pTAV320. An investigation of the possible interactions between both replication systems was performed using molecular analysis in the parental composite plasmid pTAV1. Results demonstrated that the two replicator regions of pTAV1 were incompatible with the parental plasmid but were compatible in trans in Paracoccus versutus cells.
