Abstract

E. coli promoters which are coordinately regulated in response to amino acid limitation contain conserved nucleotide sequences immediately 3' to -10 region. These sequences contain predominantly either GC or AT residues depending on whether the response is respectively negative or positive. Certain classes of promoters also contain conserved sequences upstream of the primary promoter. In tRNA genes these sequences could act as a secondary polymerase binding site.
