ECF RNA polymerase sigma factor SigK

UniProtKB accession:  P9WGH7

Grouped By:  Matching UniProtKB accession

UniProtKB description:  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 an anti-sigma factor until released by regulated intramembrane proteolysis. Sigma-K controls genes such as mpt70 and mpt83.
