Circadian input-output histidine kinase CikA

UniProtKB accession:  Q8DKG0

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Functions in an input pathway to the Kai circadian clock. Senses oxidized quinones via its C-terminal pseudo-receiver domain, providing a link between cell metabolism and the clock. Affects the ratio of phosphorylated to unphosphorylated KaiC, binds quinones via its pseudo-receptor domain. Quinone-binding destabilizes the protein rapidly. Autophosphorylates, does not transfer the phosphate to its pseudo-receiver (PsR) domain. May play a role in cell division.
