Protein attributes

Sequence length	285 AA.
Sequence status	Complete.
Protein existence	Inferred from homology

General annotation (Comments)

Function	Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released. This sigma factor is responsible for the expression of heat shock promoters By similarity.
Sequence similarities	Belongs to the sigma-70 factor family. Sigma-32 subfamily.
