- These E. coli operons are regulated by CRP as well as by an adjacent regulator and have been co-transferred, together with their neighbor regulators, between the E. coli lineage and other γ-Proteobacteria. We used a weight matrix to identify potential binding sites for CRP upstream of these operons and their xenologs. For each site we report its sequence, its score in bits, and its position relative to the start codon of the first gene in the operon. The sites that were used to build the weight matrix have 8.41 ± 2.66 bits (mean ± standard deviation). Within each site's sequence, positions that match the consensus nAnTGTGAnnnnnnTCACAnTn are capitalized.
