Abstract excerpt
The RNA polymerase sigma factor sigma N (sigma 54) is characterized by the presence, near the C-terminal end of the protein, of a highly conserved sequence of 10 amino acids (ARRTVAKYRE) that has been termed the RpoN box. In order to examine the function of this motif, which is predicted to adopt an alpha-helical structure, we have isolated a number of mutations that alter residues within the box and examined the...
