Protein
RNA polymerase sigma factor SigY
Organism
Bacillus subtilis (strain 168)
Function
Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released. Positively regulates the expression of the sigY-yxlCDEFG operon upon nitrogen starvation. Also positively regulates ybgB.
Similarity
Belongs to the sigma-70 factor family. ECF subfamily.
