Transcription Initiation in the Histidine Operon of Salmonella typhimurium*

AUTOR(ES)
RESUMO

Evidence is presented for two natural transcription initiators positioned internally in the histidine operon of Salmonella typhimurium. They were detected using highly polar S. typhimurium his mutants as recipients for F′ Escherichia coli his episomes. These intergeneric complementation tests provide a sensitive method for the detection of other initiators and of terminators.
