Protein
RNA polymerase sigma factor sigD, chloroplastic
Organism
Arabidopsis thaliana
Length
419 amino acids
Function
Sigma factors are initiation factors that promote the attachment of plastid-encoded RNA polymerase (PEP) to specific initiation sites and are then released. Regulates transcription of the ndhF gene which codes for a subunit of the plastid NDH [NAD(P)H dehydrogenase] complex.
Similarity
Belongs to the sigma-70 factor family.

Protein
RNA polymerase sigma-D factor
Organism
Bacillus subtilis (strain 168)
Length
254 amino acids
Function
Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released. This alternative sigma factor is required for the transcription of the flagellin and motility genes as well as for wild-type chemotaxis.
Similarity
Belongs to the sigma-70 factor family.

Organism
Mycobacterium bovis (strain ATCC BAA-935 / AF2122/97)
Length
212 amino acids
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.
Similarity
Belongs to the sigma-70 factor family. ECF subfamily.
