THE CRYSTAL STRUCTURE OF THE BACTERIAL CHAPERONIN GROEL AT 2.8 ANGSTROMS
Overview
The crystal structure of Escherichia coli GroEL shows a porous cylinder of, 14 subunits made of two nearly 7-fold rotationally symmetrical rings, stacked back-to-back with dyad symmetry. The subunits consist of three, domains: a large equatorial domain that forms the foundation of the, assembly at its waist and holds the rings together; a large loosely, structured apical domain that forms the ends of the cylinder; and a small, slender intermediate domain that connects the two, creating side windows., The three-dimensional structure places most of the mutationally defined, functional sites on the channel walls and its outward invaginations, and, at the ends of the cylinder.
