Diagrammatic representation of intergenic region of mce1 operon. (A)- Representation of the relative position of mce1 operon genes (within rectangles) in M.tuberculosis. Numbers above indicate the translational start site of the genes, arrows indicate the direction of transcription, filled bars indicate the intergenic regions. Figure is not drawn to scale. (B)- Mapping of the consensus motifs detected by MEME analysis of the predicted promoter sequences (IGPr). The motifs are highlighted in bold upper case. ATG is the translational start codon of Rv0167. (C, D)- Sequence logos of the two consensus sequences as given as the probability of occurrence at the given position with in the motif by the MEME software. The size of the letter indicating the strength of the consensus in the set of sequences analysed.
