Transcription of the ferric citrate transport system of Escherichia coli K-12 is mediated by the extracytoplasmic-function (ECF) sigma factor FecI, which is activated by ferric citrate in the growth medium. By using a bacterial two-hybrid system, it was shown in vivo that FecI binds to the beta' subunit of RNA polymerase. The inactive mutant protein FecI(K155E) displayed reduced binding to beta', and small deletions along the entire FecI protein led to total impairment of beta' binding. In… CONTINUE READING
