Abstract:
A stable complex of the chaperonins, cpn60 and cpn10 (Escherichia coli GroEL and GroES homologues), from the extremely thermophilic bacterium Thermus thermophilus has been isolated and crystallized. The crystals have dimensions up to 30 x 200 x 200 microns. Ultra-thin sections of the crystals estimated by electron microscopy showed a rectangular lattice with unit cell parameters of a = 17 nm, b = 27 nm, gamma = 90 degrees.
