The Database for Aligned Ribosomal Complexes (DARC) site provides a resource for directly comparing the structures of available ribosomal complexes.
The site offers a collection of files deposited in the
RCSB protein data bank and the Electron Microscopy Data Bank,
which have been aligned so as to make direct comparison of the structures possible.
