Copper-Induced Oligomerization of CeruloplasminCrystallography Reports - Tập 66 - Trang 828-832 - 2021
M. V. Petoukhov, A. V. Sokolov, V. A. Kostevich, V. R. Samygina
Oligomerization of copper-containing ferroxidase of ceruloplasmin in the presence of protein-unbound copper in a solution has been investigated by small-angle X-ray scattering (SAXS). Ceruloplasmin is a monomer with a molecular weight of ~132 kDa. Copper chloride added in a concentration of 10 μM leads to dimerization of 60% of protein. According to the analysis of intersubunit contacts, dimerizat...... hiện toàn bộ
Thermophysical processes during sapphire crystal growth by the horizontal Bridgman methodCrystallography Reports - Tập 53 - Trang 331-335 - 2011
G. A. Lebedev, S. P. Malyukov, V. A. Stefanovich, D. I. Cherednichenko
A model problem has been formulated which served as a basis for analysis and estimation of the parameters determining the character of heat and mass transfer processes in all stages during production of sapphire crystals by the horizontal Bridgman method.
Circular dichroism spectra of synthetic amethyst crystalsCrystallography Reports - Tập 50 - Trang 461-464 - 2005
V. I. Burkov, A. V. Egorysheva, Yu. F. Kargin, A. A. Mar’in, E. V. Fedotov
The axial circular-dichroism spectrum of a synthetic amethyst crystal has been studied for the first time. Bands both of the positive and negative signs are revealed. New information on the color centers of amethyst and their electronic structure is obtained.
Crystal structure of nacrite from the electron diffraction dataCrystallography Reports - - 2008
A. P. Zhukhlistov
The crystal structure of the nacrite mineral of the kaolin group (space group Cc; R = 2.76%; 634 unique reflections) is refined from the digital oblique-texture electron diffraction patterns obtained with the use of imaging plates. The maxima characterizing the locations and potentials of the hydrogen atoms of the hydroxyl groups are revealed from the difference Fourier-potential syntheses. The O-...... hiện toàn bộ
