The complete nucleotide sequence for the Escherichia coli genome was examined, using a set of 5 different DNA structural parameters: base-stacking interactions, intrinsic DNA curvature, DNA flexibility, rigidity (propeller twist), and complexity.  We have found preferential localisation of sequences prone towards unique structures within intergenic regions.  Furthermore, there are certain areas of the genome which might serve as centers for chromatin organisation, based on the presence of regions of unusual DNA motifs.  A comparison of these global structural
features with other bacterial genomes is also presented.
