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 the xylCAB operon and the xylS gene. The open complex (sigma-54 and core RNA polymerase) serves as the receptor for receipt of the melting signal from the remotely bound activator protein XylR for the expression of the xylCAB operon and xylS.

Sequence similarities

Belongs to the sigma-54 factor family.
