Abstract excerpt

Cyanobacteria are among the simplest organisms that show daily rhythmicity. Their circadian rhythms consist of the localization, interaction, and accumulation of various proteins, including KaiA, KaiB, KaiC, and SasA. We have determined the 1.9-angstroms resolution crystallographic structure of the cyanobacterial KaiB clock protein from Synechocystis sp. PCC6803. This homotetrameric structure reveals a novel KaiB...
