Toshihiro MORIGA, Kichiro KOTO1993Volume 35Issue 1 Pages 1-6

JOURNAL FREE ACCESSAnalyses of pyrochlore-and fluorite-type oxide ion conductors Zr2Gd2O7 were made by means of X-ray diffraction, Raman spectroscopy and EXAFS method. Sharp fundamental and diffuse superstructure reflections of the pyrochlore-type phase are interpreted by assuming that anti-phase domain boundaries lie parallel to the {112} . Raman spectrum of the fluorite-type Zr2Gd2O7 was very similar to that of the pyrochlore-type one, which implies that the coordination states of the former are close to those of the latter. At 500°C, formation of Frenkel-type defects was observed in the pyrochlore-type Zr2Gd2O7.View full abstractDownload PDF (1876K) -
Tadashi HATA1993Volume 35Issue 1 Pages 7-13

JOURNAL FREE ACCESSThe three-dimensional arrangement of biologically essential functionality has been called a topographical pharmacophoric pattern. The 2-D matrix comprised of the interatomic distances of the pharmacophoric pattern reflects the 3-D arrangement of the pattern. The geometrical matching system utilizing this 2-D matrix instead of the 3-D structure has been established to save the computation time. Application of the system to the study of angiotensin-converting enzyme inhibitor and anti-inflammatory drug in Cambrige crystal data base are summarized.View full abstractDownload PDF (586K) -
So IWATA, Takahisa OHTA1993Volume 35Issue 1 Pages 14-20

JOURNAL FREE ACCESSThe three-dimensional structure of allosteric L-lactate dehydrogenase from Bildobacterium longum, the first example of a T-state structure of L-lactate dehydrogenase, has been determined to 2.0Å. A comparative study of this structure with the previously reported R-state structure from Bacillus stearothermophilus has revealed the allosteric activation mechanism of the bacterial L-lactate dehydrogenase. The fructose 1, 6-bisphosphate-induced conformational change at the effector site and the substrate affinity change at the active site are clearly shown at a molecular level. Coupling of these changes can be simply explained by a set of concerted rotations between subunits in the tetramer of the enzyme.View full abstractDownload PDF (921K) -
Ken YUKINO1993Volume 35Issue 1 Pages 21-25
Published: February 25, 1993
Released on J-STAGE: September 30, 2010
JOURNAL FREE ACCESSA new type of scanning X-ray diffracto-microscope (SXDM) /X-ray powder diffractometer (XPD) which uses a converged incident beam, was designed, manufactured, and some of its basic characteristics were examined. The optical system consists of two asymmetric reflection type curved crystal monochromators for both incident and reflection beams, a PSPC and a translation mechanism for the specimen.View full abstractDownload PDF (3179K) -
