Electron micrographs and x-ray diffraction patterns of crystals of ribulose bisphosphate carboxylase, probably the most abundant protein on earth, have provided new details of the arrangement of subunits. The eight large subunits and eight small subunits are clustered in two layers, perpendicular to a fourfold axis of symmetry. Viewed down the fourfold axis, the molecule is square-shaped.
