Function
[RSBX_BACSU] Negative regulator of sigma-B activity. Dephosphorylates RsbS. Plays a role both in maintaining low sigma-B activity during growth and in reestablishing prestress sigma-B activity after induction. Could have a negative feedback role by indirectly communicating sigma-B protein levels.[1] [2] [3] [4]
