a
A, alanine; D, aspartic acid; G, glycine; K, lysine; L, leucine; N, asparagines; P, proline; Q, glutamine; S, serine. Results shown in boldface indicate relevant changes in the amino acid sequence of the RpoS protein.
b
Strain with an 843-bp deletion, including the first 174 bp of the rpoS open reading frame.
