We report here that phased runs of adenines and thymines are very frequent in the neighborhood of 3′ of the coding regions of Escherichia coli and Bacillus subtilis. These findings suggest that the DNA curvature could affect transcription termination either directly, through contacts with RNA polymerase, or indirectly, via contacts with some regulatory proteins.
