The circadian clock is an endogenous timing mechanism in living organisms that coordinates their lives with environmental changes. Cyanobacteria are the simplest organisms that are known to exhibit circadian rhythms, and they have become one of the most successful model organisms for circadian biology. Although the circadian clock in cyanobacteria has the same fundamental features as that in eukaryotes, its individual components that have been identified to date are unique. The molecular mechanism of the cyanobacterial clock is different from that described for the eukaryotic clock. The clock core in cyanobacteria is the KaiC phosphorylation cycle read more ...
