Background Circadian rhythms, observed across all domains of life, enable organisms to
anticipate and prepare for diel changes in environmental conditions. In bacteria, a circadian …

Circadian clocks are phylogenetically widespread biological oscillators that allow organisms
to entrain to environmental cycles and use their steady-state phase relationship to anticipate …

INTRODUCTION Circadian clocks provide an internal representation of local time inside
cells and control the timing of gene expression in anticipation of sunrise and sunset. In …

Diel cycle is of enormous biological importance as it imposes daily oscillation in
environmental conditions, which temporally structures most ecosystems. Organisms …

Living systems regulate many aspects of their behaviour through periodic oscillations of
molecular concentrations, which function as 'biochemical clocks.'The chemical reactions that …

Abstract Proteins KaiA, KaiB and KaiC constitute a biochemical circadian oscillator in the
cyanobacterium Synechococcus elongatus. It has been reported kaiA inactivation …

Timing is everything. Many organisms across the tree of life have evolved timekee**
mechanisms that regulate numerous of their cellular functions to optimize timing by …

Circadian clocks display remarkable reliability despite significant stochasticity in
biomolecular reactions. We study the dynamics of a circadian clock-controlled gene at the …

As the only circadian oscillator that can be reconstituted in vitro with its constituent proteins
KaiA, KaiB, and KaiC using ATP as an energy source, the cyanobacterial circadian oscillator …

Circadian clocks evolved in diverse organisms as an adaptation to the daily swings in
ambient light and temperature that derive from Earth's rotation. These timing systems, based …
