Figure 5. — Putative PHO boxes in the E. coli genes glnH and glnL. (A) Alignment of the 25 direct repeat units (DRu) that form the known binding sites of PhoB (the orthologue regulator of Streptomyces PhoP), and the logo (28) that depicts the ‘information theory’ model. Information contents (R_i) of each DRu and site are shown. (B) Putative PHO boxes (composed of 2 DRu) found in the promoter regions of glnHPQ operon (glutamine permease) and glnLG (ntrBC) operon. Walkers and R_i values are determined by the model depicted above. Positions are referred to the translation start codon.
