摘要：

The chaperonin GroEL-GroES (GroEL/ES) complex from a thermophilic eubacteria, Thermus thermophilus HB8, has been purified and crystallized. The GroEL/ES complex is known to be composed of 14 identical GroEL subunits (58 kDa) and seven identical GroES subunits (11 kDa). The GroEL/ES complex crystals belong to the triclinic space group P1, with unit-cell parameters a=140.4, b=156.4, c =273.1 Angstrom, alpha=82.9, beta=85.4, gamma=68.5degrees. The crystal asymmetric unit contains two molecules (MW=885 kDa). One data set to 3.0 Angstrom resolution, with 383 652 independent observations (89.3% complete) and an R-merge of 0.08, has been collected from a single crystal. A molecular-replacement solution was obtained using the structure of the GroEL/ES complex from Escherichia coli as a search model.
