The AAA(+) family member KaiC is the central pacemaker for circadian rhythms in the cyanobacterium Synechococcus elongatus. Composed of two hexameric rings of adenosine triphosphatase (ATPase) domains with tightly coupled activities, KaiC undergoes a

Circadian clocks control gene expression to provide an internal representation of local time. We report reconstitution of a complete cyanobacterial circadian clock in vitro, including the central oscillator, signal transduction pathways, downstream t

Hidden conformations differentiate day and night in a circadian pacemaker
Autor: Dustin C. Ernst, Diana Etwaru, Colby R. Sandate, Archana G. Chavan, Carrie L. Partch, Susan S. Golden, Jeffrey A. Swan, Gabriel C. Lander, Joseph G. Palacios, Andy LiWang, Alfred M. Freeberg
The AAA+ protein KaiC is the central pacemaker for cyanobacterial circadian rhythms. Composed of two hexameric rings with tightly coupled activities, KaiC undergoes changes in autophosphorylation on its C-terminal (CII) domain that restrict binding o

Structural mimicry confers robustness in the cyanobacterial circadian clock
Autor: Sarvind Tripathi, Jeffrey A. Swan, Dustin C. Ernst, Joel Heisler, Cigdem Sancar, Andy LiWang, Susan S. Golden, Clive R. Bagshaw, Rebecca K. Spangler, Carrie L. Partch, Priya Crosby, Joseph G. Palacios
The histidine kinase SasA enhances robustness of circadian rhythms in the cyanobacterium S. elongatus by temporally controlling expression of the core clock components, kaiB and kaiC. Here we show that SasA also engages directly with KaiB and KaiC pr

Differential catalytic promiscuity of the alkaline phosphatase superfamily bimetallo core reveals mechanistic features underlying enzyme evolution
Autor: Artem Y. Lyubimov, Jeffrey A. Swan, Tzanko Doukov, Daniel Herschlag, Ishraq AlSadhan, Fanny Sunden
Publikováno v: Journal of Biological Chemistry. 292:20960-20974
Members of enzyme superfamilies specialize in different reactions but often exhibit catalytic promiscuity for one another's reactions, consistent with catalytic promiscuity as an important driver in the evolution of new enzymes. Wanting to understand
