"Slow and temperature-compensated autonomous disassembly of KaiB–KaiC complex"

【Significance】
In both prokaryotes and eukaryotes, circadian clock proteins are assembled and frozen into highly stable hetero-multimeric complexes at night, but they are disassembled autonomously at dawn to terminate internal biological night. In this study, we experimentally determined the time scale and temperature dependence of the autonomous disassembly of the KaiB–KaiC complex, one of the major clock-protein complexes in the cyanobacterial circadian clock system. Our results clearly demonstrate that the timing of KaiB release from KaiC and its temperature dependence are governed by the structure and physicochemical state of KaiC.
