Disease relevance of pstS

PhoB protein is the transcriptional activator for genes in the phosphate regulon of Escherichia coli, such as phoA and pstS, that are induced by phosphate deprivation [1].

High impact information on pstS

The reconstituted mutant RNA polymerase holoenzymes were severely defective in transcribing the pstS gene, one of the pho genes, whereas they were efficient in transcribing the PhoB-independent promoters [2].
The phosphorylation of PhoB protein occurred concurrently with the acquisition of the ability to activate transcription from the pstS promoter [1].
It binds specifically to the DNA fragment containing the promoter region of pstS [3].
Two specific transcripts were detected, a 4.7-kb polycistronic mRNA spanning the whole operon and a quantitatively dominating 1.2-kb mRNA representing the first gene, pstS [4].
This APEC fimbrial gene cluster, which we have termed stg, is a member of a distinct group of related fimbriae that are located in the glmS-pstS intergenic region of certain E. coli and S. enterica strains [5].
