Protein

Transducer protein CosT

Gene

cosT

Organism
Halobacterium salinarum (strain ATCC 700922 / JCM 11081 / NRC-1) (Halobacterium halobium)
Status
Reviewed - Annotation score: 3 out of 5- Protein inferred from homologyi

Functioni

Mediates chemotaxis towards compatible osmolytes. Probably transduces the signal from the substrate-binding protein CosB to the histidine kinase CheA (By similarity).By similarity
