| Research Abstract |
The transcription of LEE genes in EHEC is under the positive control of PchABC, which are encoded by the genes dispersed on the chromosome. We identified transcriptional start sites and promoter sequences of each gene. Genetic analysis using transposon mutagenesis identified that a LysR-type regulator, LrhA positively controls LEE gene expression through the transcriptional up-regulation of pchA and pchB.
