Protein
Regulator of sigma-W protease RasP
Organism
Bacillus subtilis (strain 168)
Function
Is responsible for site-2 cleavage of the RsiW anti-sigma factor (PubMed:15130127). This results, after a third proteolytic step catalyzed by the ClpXP protease, in the release of SigW and the transcription activation of the genes under the control of the sigma-W factor (PubMed:16899079). Can also cleave liberated signal peptides of PenP and Mpr, probably within in the cell membrane (PubMed:21810987).
Similarity
Belongs to the peptidase M50B family.
