GntP is the Escherichia coli Fructuronic acid transporter and belongs to the UxuR regulon.

Escherichia coli has four gluconate transporters, GntP, GntU, GntT, and IdnT, which are members of the major facilitator superfamily. The physiological function of GntP was previously unknown and is the subject of this study. GntP is not induced by gluconate, and despite being located adjacent to genes involved in glucuronate catabolism, gntP does not encode a glucuronate transporter. Here we i...

The gntP gene of Escherichia coli involved in gluconate uptake.

The gntP gene, located between the fim and uxu loci in Escherichia coli K-12, has been cloned and characterized. Nucleotide sequencing of a region encompassing the gntP gene revealed an open reading frame of 447 codons with significant homology to the Bacillus subtilis gluconate permease. Northern (RNA) blotting indicated that the gntP gene was monocistronic and was transcribed as an mRNA with ...

Characterization of the Escherichia coli s Regulon*

Escherichia coli responds to the accumulation of misfolded proteins by inducing the transcription of heat shock genes. Es RNA polymerase controls one of the two heat shock regulons of E. coli. This regulon is activated upon accumulation of misfolded polypeptides in the double membrane envelope of E. coli. s (RpoE) is a member of the extracytoplasmic function subfamily of sigma factors. Here we ...

The Pho regulon and the pathogenesis of Escherichia coli.

During the course of infection, bacteria must coordinately regulate gene expression in response to environmental stimuli. The phosphate (Pho) regulon is controlled by the two component-regulatory system PhoBR. PhoBR is activated during starvation and regulates genes involved in phosphate homeostasis. Several studies have highlighted the importance of the Pho regulon in bacterial pathogenesis, s...
