Analysis of the Ferric Citrate Transport Gene Promoter of Escherichia coli

Autor: Sabine Enz, Claudia Menzel, Susanne Mahren, Volkmar Braun

Publikováno v: Journal of Bacteriology. 185:2387-2391

FecI, an extracytoplasmic-function σ factor, is required for initiation of transcription of the ferric citrate transport genes. A mutational analysis of the fecA promoter revealed that the nonconserved −10 region and a downstream regulatory elemen

Control of the Ferric Citrate Transport System of Escherichia coli : Mutations in Region 2.1 of the FecI Extracytoplasmic-Function Sigma Factor Suppress Mutations in the FecR Transmembrane Regulatory Protein

Transcription of the ferric citrate transport genes is initiated by binding of ferric citrate to the FecA protein in the outer membrane of Escherichia coli K-12. Bound ferric citrate does not have to be transported but initiates a signal that is tran

Surface signaling in ferric citrate transport gene induction: interaction of the FecA, FecR, and FecI regulatory proteins

Autor: Volkmar Braun, Uwe H. Stroeher, Sabine Enz, Susanne Mahren

Publikováno v: Journal of bacteriology. 182(3)

InEscherichia coli, transcription of the ferric citrate transport genesfecABCDEis controlled by a novel signal transduction mechanism that starts at the cell surface. Binding of ferric citrate to the outer membrane protein FecA initiates a signal tha

Surface signaling in transcriptional regulation of the ferric citrate transport system of Escherichia coli: mutational analysis of the alternative sigma factor FecI supports its essential role in fec transport gene transcription

Autor: Sabine Enz, Volkmar Braun, Annemarie Angerer, Martina Ochs

Publikováno v: Moleculargeneral genetics : MGG. 250(4)

Ferric citrate induces transcription of the ferric citrate transport genes (fec) in escherichia coli by binding to the outer membrane receptor protein FecA without entering the cell. The signal elicited by ferric citrate crosses the outer membrane vi

Transcriptional regulation of ferric citrate transport in Escherichia coli K-12. Fecl belongs to a new subfamily of sigma 70-type factors that respond to extracytoplasmic stimuli

Autor: Volkmar Braun, Annemarie Angerer, Sabine Enz, Martina Ochs

Publikováno v: Molecular microbiology. 18(1)

Transcription of the ferric citrate transport system of Escherichia coli K-12 is repressed by Fe(2+)-Fur and activated by ferric citrate. Ferric citrate does not have to enter the cytoplasm; it initiates a signal transduction mechanism by binding to
