摘要：

During 1994 and 1995, the structures of the serum amyloid P component, the bacterial chaperonin GroEL, the 20S proteasome, the bacterial light-harvesting complexes and the tryptophan operon RNA-binding attenuation protein have been determined. These structures all form circular assemblies in which the individual subunits are related by rotational symmetry. In most cases the circular organization generates a new biophysical property and a specific biological function which have presumably been selected by evolution.
