Protein
Sigma-w pathway protein YsdB
Organism
Bacillus subtilis (strain 168)
Function
May mediate a negative feedback loop that down-regulates the expression of the sigma-W regulon following the activation of sigma-W in response to conditions of cell envelope stress. Might interact with and inhibit the activity of the protease PrsW, or could bind to the anti-sigma-W factor RsiW and thereby protect it from PrsW-mediated cleavage.
