Overall free energy profile around bacterial TSS The figure shows the average free energy profiles of A) Escherichia coli (227 promoters) and B) Bacillus subtilis (89 promoters) C) Corynebacterium glutamicum promoters (28 promoters). The profiles extend from 500 nt upstream to 500 nt downstream of transcription start site (positioned at 0, shown as dashed line). The nucleotide sequence position is shown on x-axis. More negative values of free energy indicate greater stability.
