Fig 1. The aatPABC operon of ETEC H10407.

Fig 1

Schematic of the aatPABC operon and adjacent tnpA gene. The two DNA strands are shown as black lines. Known genes are shown as black arrows and the predicted aatS gene as a grey arrow. Gene names are shown in italic and gene function in parenthesis. The position of a putative CRP binding site is indicated by striped ovals. A. Sequence if the tnpA-aatC intergenic region. The CRP site is highlighted as a striped rectangle with the two half sites highlighted bold. The start codon of the aatS open reading frame is highlighted with a grey rectangle. The transcription start site, as determined by mRNA primer extension is denoted “+1” and indicated by a bent arrow. Distances upstream (-) and downstream (+) of this start site are numbered. The -35 and -10 hexamers are boxed, and the ribosome binding site (RBS) is underlined.
