The FecI extracytoplasmic-function sigma factor of Escherichia coli interacts with the beta' subunit of RNA polymerase.

Journal of bacteriology - 1 Mar 2003

Mahren Susanne, Braun Volkmar

Abstract excerpt

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...
