Protein
ECF RNA polymerase sigma factor EcfG
Organism
Rhodopseudomonas palustris (strain TIE-1)
Function
Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released (By similarity). Regulates expression of hpnP under a variety of stresses, including high temperature, pH stress, and presence of nonionic osmolytes (PubMed:23524612).
Similarity
Belongs to the sigma-70 factor family. ECF subfamily.
