Figure 4

Promoter sequences of C. glutamicum genes showing elevated expression at the onset of stationary phase. The transcription start sites mapped by RACE PCR assays are shown in boldfaced, capital letters. The numbers indicates the position of the transcription start site relative to the translational start codon. The deduced -10 sequences are shown in bold, the -35 elements are underlined. Nucleotides that match the proposed consensus for the -10 element of C. glutamicum are symbolized by capital letters. The consensus sequence of the -10 element of the C. glutamicum sigma factor SigA [tgngnTAtaaTgg] is shown for comparison [19].
