Figure 5.

Variation up and down stream of putative internal promoters. Box plots of the mean expression of genes upstream and downstream of the putative internal promoter in (a) documented S. coelicolor operons using our predictions, (b) random simulations of S. coelicolor operons, (c) documented E. coli operons using experimentally known internal promoters, and (d) random simulations of E. coli operons.
