Location and direction of transcription of the ptsH and ptsI genes on the Escherichia coli K12 genome.
Recombinant plasmids were constructed that carried various fragments of the DNA specifying the Escherichia coli genes ptsH and (part of) ptsI, the genes for the common components of the phosphoenolpyruvate: sugar phosphotransferase. Expression of plasmid-specified functions in minicells showed that ptsH and ptsI were transcribed clockwise. Most of the transcription of ptsI was from the ptsH promoter, but some was from a second site within or after ptsH.
