Other Details THE THREE DOMAINS FROM EACH SUBUNIT (PDB 1DER) WERE FITTED SEPARATELY INTO EM DENSITY OF WILD TYPE UNLIGANDED GROEL. THE MUTATIONS LISTED ARE PRESENT IN THE FITTED COORDINATES AND NOT IN THE MOLECULE WHICH GENERATED THE EM MAP. THE QUOTED RESOLUTION IS AT 3SIGMA - THE RESOLUTION AT FSC=0.5 IS 10.8A THIS ENTRY REPRESENTS THE COMPLETE BIOMOLECULE.
