Crystal structure of N-terminal C1 domain of KaiCCrystal structure of N-terminal C1 domain of KaiC

Structural highlights

4tl7 is a 6 chain structure with sequence from Synechococcus elongatus PCC 7942 = FACHB-805. Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance.
Method:	X-ray diffraction, Resolution 1.936Å
Ligands:	, , ,
Resources:	FirstGlance, OCA, PDBe, RCSB, PDBsum, ProSAT

Function

KAIC_SYNE7 Core component of the KaiABC clock protein complex, which constitutes the main circadian regulator in cyanobacteria. Binds to DNA. The KaiABC complex may act as a promoter-nonspecific transcription regulator that represses transcription, possibly by acting on the state of chromosome compaction.^[1] ^[2]
