Comments
[?]
| FUNCTION | Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released. This sigma factor is the master transcriptional regulator of the stationary phase and the general stress response. |
| SUBUNIT | Interacts with the RNA polymerase core enzyme. |
| SUBCELLULAR LOCATION | Cytoplasm. |
| SIMILARITY | Belongs to the sigma-70 factor family. RpoS subfamily. |
