| - | == | + | [https://www.uniprot.org/uniprot/RPOE_CERS4 RPOE_CERS4] Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released. Extracytoplasmic function (ECF) sigma factors are held in an inactive form by a cognate anti-sigma factor until released. Sigma-E controls a transcriptional response to singlet oxygen, a by-product of photosynthesis; its continuous activity requires constant exposure to singlet oxygen. The regulon has about 180 genes that protect against or repair damage induced by singlet oxygen, including itself and rpoH2, a heat shock-responsive sigma factor.<ref>PMID:11676534</ref> <ref>PMID:15855269</ref> <ref>PMID:17803943</ref> |
