Previously Reported σW-regulated genes that were not significantly down-regulated in the sigW mutant strain.

For each individual gene, the Table lists the function, the previously identified regulation, the genetic organization, the condition-dependent transcription profile cluster as defined by Nicolas et al[35], the presence of a predicted ‘σWXY’ promoter sequence [35], and our conclusion whether it belongs to the σW core regulon or the secondary σW-regulated genes. It should be noted here that the previously predicted ‘σWXY’ promoter sequence [35] also covers the potential binding site for σM.
