Protein

Sensor histidine kinase ComP

Gene

comP

Organism
Bacillus subtilis (strain 168)
Status
Reviewed-Annotation score: Annotation score: 4 out of 5-Experimental evidence at transcript leveli

Functioni

Sensor in the two-component regulatory system ComP/ComA involved in a major quorum response pathway that regulates the development of genetic competence. Plays a role in sporulation, at least partly interchangeable with that of SpoIIJ. Probably activates ComA by phosphorylation.1 Publication

Catalytic activityi

ATP + protein L-histidine = ADP + protein N-phospho-L-histidine.

Miscellaneousi

Miscellaneous

The DNA sequences encoding comQ, comX and the N-terminal two-thirds of comP show a striking polymorphism, which determines the specificity of the quorum-sensing system in the different pherotypes of Bacillus.

Similar proteinsi

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 one 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.
