Fig. 2. The 3D structures of a-LTX and d-LIT monomers. Comparison of the side and top views of the alpha-LTX monomer obtained by
single-particle analysis of cryo-electron micrographs (Orlova et al., 2000) with similar views of the d-LIT monomer, reconstructed by
single-particle analysis of negative-stain electron micrographs. The domains of alpha-LTX are marked as in (Orlova et al., 2000); tentative
domain assignments in the delta-LIT reconstruction are based on the interactive overlap of the 3D maps, fitting of ARs and volumetric
analysis. Both volumes were low-pass filtered to 20A. (J. Nield, R. Abbondati, B. Odier, A. Rohou, Y. Ushkaryov, unpublished results).
