PromEC is an updated compilation of E. coli mRNA promoter sequences. It includes documentation on the location of experimentally identified mRNA transcriptional start sites on the E. coli chromosome, as well as the actual sequences in the promoter region.
The database is currently updated as of July 2000 and includes 471 entries. [Hershberg R. et. al., reproduced with permission from NAR Online http://www.nar.oupjournals.org ]

Promoter sequences - sequences spanning nucleotides -75 to +25 relative to the transcriptional start sites
