Divalent metal ions are required virtually in every stage of genetic information transfer, and have profound effects on the structures and functions of nucleic acids. This article reviews the current developments of X-ray diffraction studies of metal ion interactions with nucleic acid constituents. The following important findings and topics are briefly presented ; metal binding sites, metal binding effects on the structural dimensions and conformations of nucleic acid constituents, molecular structures of metalnucleotide complexes, metal binding mode in ternary metal ion-nucleotide complexes containing aromatic heterocyclic ligands, which have been studied as a simple model for nucleic acid-metalion-enzyme system, and binding modes of anti-tumor agents, cisammine platinum (II) complexes with nucleic acids.

Over a past few years, we have determined crystal structures of several metal-containing oxygenases including indoleamin-2, 3-dioxygenase and some P450s which have interesting chemistry and play important roles in metabolism. Molecular mechanisms of these oxygenases are discussed based on the crystal structures.

The present paper is a brief review of our recent works on the crystal structures, structural disorders and ion-diffusion paths of various ionic and mixed conductors. Diffusion paths along the <100> directions are observed in the fluorite-type ionic conductors such as δ-Bi1.4Yb0.6O3, Ce0.93Y0.07O1.96, Y0.785Ta0.215O1.715 and α-CuI. In the prerovskite-type and double-prerovskite-type conductors, the mobile oxide ions move along the <100> directions near the stable positions and along <110> around the midway of diffusion pathway. The cubic prerovskite-type and double-prerovskite-type conductors exhibit three- and two-dimensional networks of diffusion pathways, respectively. K2NiF4-type conductor has a two-dimensional network of diffusion pathway through interstitial oxide ions. The oxide ions in apatite-type conductors diffuse along the hexagonal c-axis. The diffusion paths of two lithium-ion conductors are also presented.

Selenocysteine (Sec) is the 21st amino acid that is incorporated into proteins translationally. The selenocysteine tRNA (tRNASec) is first ligated with serine by seryl-tRNA synthetase, and the Ser moiety is converted to Sec in a tRNA-dependent manner. In Bacteria, the selenocysteine synthase SelA converts Ser to Sec directly, whereas in Eukaryotes and Archaea, phosphorylation of the Ser moiety is required prior to the Sec conversion. In this review, we describe the crystal structures of SelA, bacterial tRNASec, and the SelA•tRNASec complex. Based on the crystal structures and mutational analyses, the substrate discrimination and reaction mechanisms are discussed.

From the structural-chemical point of view, the ‘non-benzenoid aromatic compounds’ are reviewed. Hückel's (4n+2) rule has been proved by the X-ray analysis of several annulenes. It was pointed out, however, that resonance energies of non-alternant hydrocarbons are overestimated. Structural studies on the conjugated odd-membered ring systems have shown that these systems are very sensitive to various kinds of interactions, electronic, steric and intermolecular hydrogen bonding effects. The characteristic chemical and physical behaviours can be reasonably related to the structures.

PLANET is a powder neutron diffractometer dedicated to high-pressure experiments. By combining the intense neutron source of J-PARC and the high-pressure devices designed for time-of-flight powder neutron diffraction, precise structure analysis of crystal, liquid, and amorphous solids is possible over wide pressure and temperature range of 0~20 GPa and 77~2,000 K. This beamline is effective for various studies in geophysics, planetary science, physics and chemistry. This paper overviews the beamline and introduces recent results obtained at PLANET.

Nitrite ion is a well-known ligand which shows linkage isomerism. The photo-isomerization in the solid state is governed by at least two factors: (a) electronic effect by coexisting ligands, and (b) reaction cavity of the nitro group. Recent X-ray study has revealed that the nitro-nitrito photo isomerization in a crystal is severely governed by intermolecular steric restrictions.
