title: Mapping and regulation of the pifC promoter of the F plasmid.
abstract: The pif region of the F plasmid, which causes abortive infection of Escherichia coli by T7 bacteriophage, is autogenously controlled by the product of the pifC gene. Here we describe the identification of the pif operon promoter by S1-nuclease mapping, and show that it is autoregulated at the transcriptional level and that its activity is modulated by integration host factor.
