Comments P.500 bottom paragraph: "Seven different species of σ subunits, σ70, σN (also called σ54), σS (σ38), σH (σ32), σF (σ28), σE (σ24), and σFecI, have been identified in E. coli (refs 28, 29, 31, 40), each participating in transcription of a specific set of genes (Figure 1, see color insert)." P.501 3rd paragraph: "In exponential-phase cells, two of the alternative σ subunits, σN and σF, are present in significant concentrations, but, in addition, the level of σS becomes detectable in stationary phase (Figure 1, see color insert)." See note beneath figure. Please note-title of primary source [68] (but not other details such as authors and page numbers) is different between the reference and PUBMED database
