Protein

Phosphoserine phosphatase RsbX

Gene

rsbX

Organism
Bacillus subtilis (strain 168)
Status
Reviewed-Annotation score: Annotation score: 2 out of 5-Experimental evidence at protein leveli

Functioni

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.4 Publications

Catalytic activityi

O-phospho-L(or D)-serine + H2O = L(or D)-serine + phosphate.

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into Uniref entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
