Other Details RECIPROCAL SPACE FITTING OF SEVEN INDEPENDENT RIGID BODIES WITH URO. FITTED ENTITIES WERE GROEL EQUATORIAL (RESIDUES 3-136 AND 410-524), INTERMEDIATE (RESIDUES 137-192 AND 374-409) AND APICAL (RESIDUES 192-373) DOMAINS, PLUS A GROES SUBUNIT. THE MAP INTO WHICH THESE COORDINATES WERE FITTED IS AVAILABLE AT THE EMD (EMD-1180)
