Bacterial genomes are organized in terms of structural and functional components. These components include promoters, transcription start and termination sites, open reading frames, regulatory non-coding regions, untranslated regions and transcription units, that together comprise the functional organization of a genome. Here, we use a systems approach that iteratively integrates multiple high-throughput measurements at a genome-scale to identify the organizational structure of the Escherichia coli K-12 MG1655 genome. Integration of the organizational components provides experimentally annotated transcription unit (TU) architecture, including alternative transcription start sites, promoter structures, boundaries and open reading frames. A total of 4,661 TUs were identified, representing an increase of > 530% over current knowledge. This comprehensive TU architecture allows for the elucidation of condition-specific uses of alternative sigma factors at the genome-scale. Furthermore, the TU architecture provides a foundation on which genome-scale transcriptional and translational regulatory networks are based.
