Taxonomic identifier224308 [NCBI]
Taxonomic lineageBacteria › Firmicutes › Bacilli › Bacillales › Bacillaceae › Bacillus ›

Protein existenceEvidence at transcript level

General annotation (Comments)

Function

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. Ref.7

Catalytic activity

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

Subcellular location

Cell membrane; Multi-pass membrane protein.

Post-translational modification

Autophosphorylates on a histidine and transfers the phosphate group onto an aspartate in ComA, thus activating it.

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.

Sequence similarities

Contains 1 histidine kinase domain.
