Control of initiation of F plasmid replication

Initiation of F replication from ori2 depends on the plasmid-coded initiator (E protein) and other host proteins. We recently found two additional host gene products that control F replication. The rpoH gene product (σ32) is direcly involved in transcription of the repE gene encoding E protein, wher...

Summary:Initiation of F replication from ori2 depends on the plasmid-coded initiator (E protein) and other host proteins. We recently found two additional host gene products that control F replication. The rpoH gene product (σ32) is direcly involved in transcription of the repE gene encoding E protein, whereas the mafA gene product controls mini-F replication through interaction with the incC and probably incB regions. Control mechanism of initiation of F replication is reviewed.
