Protein
RNA polymerase sigma factor SigA2
Organism
Synechococcus elongatus (strain PCC 7942)
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 a component of the biological clock pathway that affects the circadian expression of a subset of genes in this bacterium.
Similarity
Belongs to the sigma-70 factor family.
