RNA polymerase sigma factor RpoD

Gene

sigA

Organism
Stigmatella aurantiaca
Status
Unreviewed-Annotation score: -Protein inferred from homologyi

Functioni

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.SAAS annotation
