    Notes: The crystal structure of the ternary complex of horse liver alcohol dehydrogenase (LADH) with the coenzyme NADH and inhibitor dimethyl sulfoxide (DMSO) has been refined by simulated annealing with molecular dynamics and restrained positional refinement using the program X-PLOR. The two subunits of the enzyme were refined independently. The space group was P1 with cell dimensions a = 51.8, b = 44.5, c = 94.6 Å, α = 104.8, β = 102.3 and γ = 70.6°. The resulting crystallographic R factor is 17.3% for 62 440 unique reflections in the resolution range 10.0–1.8 Å. A total of 472 ordered solvent molecules were localized in the structure. An analysis of secondary-structure elements, solvent content and NADH binding is presented.

    The complex perovskite-related superstructure Ba2Fe2O5 solved by HREM and CIP (1993)

    Notes: Barium ferrite Ba2Fe2O5 is a complex perovskite-related structure. The crystal is monoclinic P21/c, with a = 6.969 (1), b = 11.724 (1), c = 23.431 (5) Å, β = 98.74 (1)°. The composition of one unit cell is Ba28Fe28O70. The structure was solved using a combination of high-resolution electron microscopy (HREM), crystallographic image processing (CIP) and electron diffraction. The structure can be described as a perovskite with 14 oxygen positions unoccupied with respect to the ABO3 stoichiometry in the monoclinic unit cell. These positions can be identified from the potential map obtained by HREM and CIP. They form two linear groups. Seven of them lie on a line along [476]m (corresponding to [110]c of perovskite), while the seven other symmetry-related positions lie along [4\overline 76]m (corresponding to [101]c of perovskite).
