Life on earth is subject to daily and predictable fluctuations in light intensity, temperature,
and humidity created by rotation of the earth. Circadian rhythms, generated by a circadian …

Virtually all species have developed cellular oscillations and mechanisms that synchronize
these cellular oscillations to environmental cycles. Such environmental cycles in biotic (eg …

Cyanobacteria have a robust circadian oscillator, known as the Kai system. Reconstituted
from the purified protein components KaiC, KaiB, and KaiA, it can tick autonomously in the …

The oscillator of the circadian clock of cyanobacteria is composed of three proteins, KaiA,
KaiB, and KaiC, which together generate a self-sustained∼ 24-h rhythm of phosphorylation …

Recent studies have unveiled the molecular machinery responsible for the biological clock
in cyanobacteria and found that it exerts pervasive control over cellular processes including …

Genetically encoded biological clocks are found broadly throughout eukaryotes and in
cyanobacteria, where they generate circadian (about a day) rhythms that allow organisms to …

The circadian oscillator of cyanobacteria is composed of only three proteins, KaiA, KaiB, and
KaiC. Together, they generate an autonomous~ 24-h biochemical rhythm of phosphorylation …

Circadian timing in cyanobacteria is determined by the Kai system consisting of KaiA, KaiB,
and KaiC. Interactions between Kai proteins change the phosphorylation status of KaiC …

Cyanobacteria have become a major model system for analyzing circadian rhythms. The
temporal program in this organism enhances fitness in rhythmic environments and is truly …
