Molecular‐Dynamics Simulations for Amyloid β1–42 Monomer with D‐Aspartic Acid Residues Using Continuous Solvent
Authors: Oda Akifumi , Kobayashi Kana , Takahashi Ohgi 
Published: June 2010

AbstractMolecular‐dynamics simulations of amyloid‐β1–42 peptides including D‐aspartic acid residues were performed, and their three‐dimensional structures were compared. The simulations were performed in an aqueous environment using a continuous solvent model. In the structures obtained from simulations, the occurrence ratio of β‐extended structures for the peptide that included D‐Asp23 was larger than that for the wild‐type peptide. These β‐extended structures appeared in the C‐terminal region of the peptide, and the α‐helix structures of the region were lost. On the other hand, for the peptide that included the stereo‐inverted form of Asp1 as well as D‐Asp23, the occurrence ratio of β‐extended structures in the C‐terminal region was lower than that of the peptide including only D‐Asp23.

AbstractD‐Amino acid oxidase (DAO) catalyzes oxidative deamination of D‐amino acids. Since D‐amino acids are considered to be rare in eukaryotes, physiological function of this enzyme has been enigmatic for a long time. Mutant mice lacking DAO were found, and their strain was established. The urine of the mutant mice contained large amounts of D‐amino acids. D‐Amino acids were also present in their organs and blood. The origin of these D‐amino acids was pursued. The results indicate that one of the physiological functions of DAO is the metabolism of D‐amino acids of internal and external origin. A large amount of D‐serine is shown to exist in the brain of mammals. It binds to the coagonist‐binding site of N‐methyl‐D‐aspartate (NMDA) subtype of glutamate receptors and enhances the neurotransmission. DAO metabolizes this D‐serine and, therefore, modulates neurotransmission. Mutant mice displayed phenotypes resulting from the enhanced NMDA receptor function. Recent studies have shown that DAO is associated with schizophrenia. Mutant mice were resistant to the drugs which act on NMDA receptors and elicit schizophrenia‐like symptoms. Recently, mutant rats lacking DAO have also been found. They were free from D‐serine‐induced nephrotoxicity, indicating involvement of DAO in this toxicity. The mutant mice and rats lacking DAO would be useful for the elucidation of the physiological functions of DAO and the etiology of neuronal diseases associated with DAO.

AbstractDuring storage of shell eggs, an egg‐white protein, ovalbumin is converted into a molecular species with higher thermostability (ΔTm=8°), which is named as S‐ovalbumin. Since the pH of egg white is raised to 9.5 in that process, particular chemical modifications could occur. Although any evidence for relationship between chemical modifications and the thermostabilization had not been established, our X‐ray crystallographic model for S‐ovalbumin demonstrated that three serine residues (S164, S236, and S320) might be in D‐configuration. Then, whether these serine residues contribute to the thermostabilization in S‐ovalbumin is investigated by protein‐engineering approach. By alkaline treatment, S236G mutant was converted to a more thermostable form, as well as ovalbumin has been converted to S‐ovalbumin. Hence, the Ser236 is regarded to have no contribution to S‐ovalbumin formation. On the contrary, S164G and S320G did show accelerated conversion to thermostable forms in comparison with ovalbumin or wild‐type recombinant protein. When these residues were replaced with valine, which has a slower racemization rate, ΔTm after alkaline treatment had become half of that for the wild‐type recombinant ovalbumin. Therefore, the process of S‐ovalbumin formation is deduced to consist of two steps, which is closely related to the two serine residues.

AbstractLi‐doped MgO is a potential catalyst for the oxidative coupling of methane, whereby surface Li+ O− centers are suggested to be the chemically active species. To elucidate the role of Li in the MgO matrix, two model systems are prepared and their morphological, optical and magnetic properties as a function of Li doping are investigated. The first is an MgO film deposited on Mo(001) and doped with various amounts of Li, whereas the second is a powder sample fabricated by calcination of Li and Mg precursors in an oxygen atmosphere. Scanning tunneling and transmission electron microscopy are performed to characterize the morphology of both samples. At temperatures above 700 K, Li starts segregating towards the surface and forms irregular Li‐rich oxide patches. Above 1050 K, Li desorbs from the MgO surface, leaving behind a characteristic defect pattern. Traces of Li also dissolve into the MgO, as concluded from a distinct optical signature that is absent in the pristine oxide. No electron paramagnetic resonance signal that would be compatible with Li+O− centers is detected in the two Li/MgO samples. Density‐functional theory calculations are used to determine the thermodynamic stability of various Li‐induced defects in the MgO. The calculations clarify the driving forces for Li segregation towards the MgO surface, but also rationalize the absence of Li+O− centers. From the combination of experimental and theoretical results, a detailed picture arises on the role of Li for the MgO properties, which can be used as a starting point to analyze the chemical behavior of the doped oxide in future.

AbstractThe influence of the highly dispersed gold phase on the CO–support interaction occurring in two 2.5 wt % Au/Ce0.62Zr0.38O2 catalysts with medium (Au/CZ‐MD) and high (Au/CZ‐HD) metal dispersion is quantitatively assessed. For this purpose, we have followed an approach in which high‐angle annular dark‐field scanning transmission electron microscopy (HAADF‐STEM), computer modelling, volumetric adsorption and FTIR spectroscopy studies are combined. This approach has already been fruitfully applied to the investigation of the specific CO–metal adsorption in Au/ceria–zirconia catalysts. As deduced from the experimental studies reported herein, the presence of gold dramatically increases the amount of CO strongly chemisorbed on the support. Moreover, this amount is sensitive to the metal dispersion, thus suggesting the occurrence of a mechanism in which the CO molecules that are initially adsorbed on the gold nanoparticles are further transferred to the support by means of a spillover process. An annular model is proposed for the growth of the CO phase adsorbed on the ceria–zirconia mixed oxide in the presence of Au. By assuming this model, we have estimated the width of the annulus, Δr, of the adsorbed CO grown around the Au nanoparticles in Au/CZ‐MD and Au/CZ‐HD catalysts. This value is found to be very close to Δr≈2 nm in both cases, the coincidence lending some additional support to the model. To further confirm this proposal, we have investigated the influence of CO pre‐adsorption on the D2–Au/CZ‐MD interaction, at 298 K. As revealed by FTIR spectroscopy, the kinetics of the deuterium spillover is significantly disturbed by the pre‐adsorbed CO, which is fully consistent with an annular model for the CO adsorption. We conclude from the global analysis of the results reported here and those already available on CO–Au adsorption that the appropriate combination of nanostructural, computer modelling and chemical techniques is a powerful tool allowing us to gain a comprehensive picture of the complex series of processes involved in the CO adsorption on this relevant family of gold catalysts.
