ABSTRACT
KaiC is the central protein in the circadian rhythm in cyanobacteria. The 28â
kDa KaiC-like protein PH0187 from the hyperthermophilic archaeon Pyrococcus horikoshii was expressed in Escherichia coli, purified and crystallized using the sitting-drop vapour-diffusion method at 293â
K. Crystals of PH0187 were obtained using a reservoir solution consisting of 1.0â
M ammonium phosphate monobasic and 0.1â
M sodium citrate tribasic pH 5.3 (the final pH value of the reservoir solution was 4.8) and diffracted X-rays to 2.75â
Å resolution. The crystal of PH0187 belonged to space group P6(3)22, with unit-cell parameters a=b=239.1, c=106.5â
Å. The crystal contained four PH0187 molecules in the asymmetric unit.
