Protein
ECF RNA polymerase sigma factor SigD
Organism
Mycobacterium tuberculosis (strain CDC 1551 / Oshkosh)
Function
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 (By similarity).
Similarity
Belongs to the sigma-70 factor family. ECF subfamily.
