The Profiling of Escherichia coli chromosome (PEC) database has been constructed to compile any relevant information that could help to characterize the E. coli genome, especially with respect to discovering the function of each gene. The database is intended to provide an interface comprehensible to most experimental researchers. PEC is based on the sequence information of E. coli strain MG1655. Information, such as basic information (gene name, direction, length, location, etc.) about each gene, was retrieved from the other databases and annotated before incorporation into the PEC database. The genome is displayed as a circle or linearly. Structural domains and motifs of a gene product are displayed graphically along with those of other genes having the same domains or motifs.
