== Function == | |||
[https://www.uniprot.org/uniprot/SIGA_THEAQ SIGA_THEAQ] 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 primary sigma factor during exponential growth.[HAMAP-Rule:MF_00963]<ref>PMID:11114902</ref> <ref>PMID:11931761</ref> | |||
