Abstract

We have obtained 2-dimensional crystals of the beta-subunits of the chaperonin TF55 from Sulfolobus shibatae reconstituted into oligomers in the absence of alpha-subunits. The subunits form rings with 9-fold rotational symmetry which arrange themselves in a trigonal lattice. From electron micrographs of negatively stained specimens we have calculated a projection map in plane group p312 showing the rings in top-view.
