RK600 helper plasmid

Introduction

pRK600 carries the tra genes, which are necessary for conjugative transfer. These genes enable the mobilization of plasmids between bacteria, facilitating the transfer of the transposon-bearing plasmid from the donor strain to the recipient strain via conjugation [1].


Usage and Biology

The RK600 plasmid, used in E. coli HB101, plays a key role in the mini Tn-7 system by carrying the tra genes necessary for conjugative transfer. These genes enable the mobilization of plasmids between bacteria, facilitating the transfer of the transposon-bearing Tn7 plasmid from a donor strain, like E. coli PIR2, to a recipient strain, such as Pseudomonas putida KT2440. In this system, pRK600 acts as a "helper" plasmid, providing the essential machinery for efficient conjugation, ensuring that the Tn7-M plasmid is successfully transferred, a process that would otherwise be inefficient without the involvement of pRK600 [2].

Dr. Esteban Martinez, a postdoctoral researcher at Victor de Lorenzo's Lab, provided us with the E.coli HB101 strain with the RK600 plasmid
