rsbS

Gene
rsbS
Protein
RsbT antagonist protein RsbS
Organism
Bacillus subtilis (strain 168)
Length
121 amino acids
Function
Negative regulator of sigma-B activity. Non-phosphorylated RsbS binds to RsbT, preventing its association with RsbU. Requires any one of RsbRA, RsbRB, RsbRC or RsbRD to sequester RsbT. When RsbS and the RsbR paralog(s) are phosphorylated, they release RsbT, which can then bind and activate RsbU.
