Strukturelle Einblicke in den Mo‐Cofaktor‐Einbau in Sulfitoxidase durch ortsspezifische Spinmarkierung
Authors: Hahn Aaron , Engelhard Christopher , Reschke Stefan , Teutloff Christian , Bittl Robert , Leimkühler Silke , Risse Thomas
Published: August 2015

Einkernige Molybdoenzyme katalysieren eine Vielzahl von Redoxreaktion und sind in allen Reichen des Lebens hoch konserviert. Dieser Artikel beschäftigt sich mit der Frage, wie der Molybdän‐Cofaktor (Moco) in die Apoform humaner Sulfitoxidase (hSO) eingebaut wird. Hierbei wird ortsspezifische Spinmarkierung genutzt, um intramolekulare Abstände im Nanometerbereich zu bestimmen. In vergleichenden Messungen an Holo‐ und Apoformen verschiedener Varianten von hSO wurden Strukturunterschiede festgestellt, die auf eine kurze Schleife (Reste 263–273) in der Moco‐Domäne beschränkt sind. Eine Klappbewegung dieser Schleife ermöglicht den Zugang zur Moco‐Bindungstasche in der Apoform und liefert eine mögliche Erklärung für die zuvor beobachtete In‐vitro‐Rekonstitution von Apo‐hSO mit Moco. Ein solches Bindungsmotiv kann in strukturell verwandten Molybdoenzymen in einer Reihe verschiedener Organismen identifiziert werden, was auf einen gemeinsamen Mechanismus zum Moco‐Einbau schließen lässt.
Simultane Zink‐katalysierte C‐X‐ und C‐H‐Borylierung von Arylhalogeniden
Authors: Bose Shubhankar Kumar , Deißenberger Andrea , Eichhorn Antonius , Steel Patrick G. , Lin Zhenyang , Marder Todd B.
Published: August 2015

1,2‐Diborylarene konnten durch Zink‐katalysierte C‐X‐ und C‐H‐Borylierung von Arylhalogeniden bei milden Reaktionsbedingungen unter Verwendung von B2pin2 (pin=OCMe2CMe2O) synthetisiert werden. Die katalytische C‐H‐Bindungsaktivierung erfolgt in ortho‐Position zum Halogensubstituenten, sofern diese Stelle zugänglich ist, oder in meta‐Position, falls die ortho‐Position substituiert ist. Der Prozess beinhaltet somit eine neuartige Verwendung von Gruppe‐XII‐Katalysatoren zur C‐H‐Borylierung. Die Reaktion verläuft nicht über ein freies Arin als Zwischenstufe, vielmehr scheint ein radikalischer Prozess vorzuherrschen.
A Set of Homo‐Oligomeric Standards Allows Accurate Protein Counting
Authors: Finan Kieran , Raulf Anika , Heilemann Mike
Published: August 2015

Techniques based on fluorescence microscopy are increasingly used to count proteins in cells, but few stoichiometrically well‐defined standards are available to test their accuracy. A selection of bacterial homo‐oligomers were developed that contain 10–24 subunits and fully assemble when expressed in mammalian cells, and they can be used to easily validate/calibrate molecular counting methods. The utility of these standards was demonstrated by showing that nuclear pores contain 32 copies of the Nup107 complex.
Aqueous Titanium Trichloride Promoted Reductive Cyclization of o‐Nitrostyrenes to Indoles: Development and Application to the Synthesis of Rizatriptan and Aspidospermidine
Authors: Tong Shuo , Xu Zhengren , Mamboury Mathias , Wang Qian , Zhu Jieping
Published: August 2015

Treatment of o‐nitrostyrenes with aqueous TiCl3 solution at room temperature afforded indoles through a formal reductive C(sp2)–H amination process. A range of functions such as halides (Cl, Br), carbonyl (ester, carbamate), cyano, hydroxy, and amino groups were tolerated. From β,β‐disubstituted o‐nitrostyrenes, 2,3‐disubstituted indoles were formed by a domino reduction/cyclization/migration process. Mild conditions, simple experimental procedure, ready accessibility of the starting materials and good to excellent yields characterize the present transformation. The methodology was used as a key step in a concise synthesis of rizatriptan and a formal total synthesis of aspidospermidine.
Orange Zinc Germanate with Metallic GeGe Bonds as a Chromophore‐Like Center for Visible‐Light‐Driven Water Splitting
Authors: Qian Ling , Chen Jian Fu , Li Yu Hang , Wu Long , Wang Hai Feng , Chen Ai Ping , Hu P. , Zheng Li Rong , Yang Hua Gui
Published: August 2015

The efficiency of solar‐energy‐conversion devices depends on the absorption region and intensity of the photon collectors. Organic chromophores, which have been widely stabilized on inorganic semiconductors for light trapping, are limited by the interface between the chromophore and semiconductor. Herein we report a novel orange zinc germanate (Zn‐Ge‐O) with a chromophore‐like structure, by which the absorption region can be dramatically expanded. Structural characterizations and theoretical calculations together reveal that the origin of visible‐light response can be attributed to the unusual metallic GeGe bonds which act in a similar way to organic chromophores. Benefiting from the enhanced light harvest, the orange Zn‐Ge‐O demonstrates superior capacity for solar‐driven hydrogen production.
Effective Amyloid Defibrillation by Polyhydroxyl‐Substituted Squaraine Dyes
Authors: Jayaram Dhanya T. , Shankar Balaraman H. , Ramaiah Danaboyina
Published: August 2015

With an objective to develop β‐amyloid destabilizing agents, we have investigated the interactions of a few water‐soluble near‐infrared (NIR)‐absorbing squaraine dyes 1–3 with lysozyme and its amyloid aggregates through photophysical and biophysical techniques. These dyes exhibited strong interactions with lysozyme and β‐amyloids in addition to serum albumins as evidenced by the absorption and emission changes. The interactions were found to be spontaneous with association constant values in the range of approximately 104–105 m−1, as confirmed through half‐reciprocal analysis and isothermal calorimetric measurements. Uniquely, such effective interactions of the dyes have led to the complete disassembly of the β‐amyloid fibrillar structures to form spherical particles approximately 350 nm in size, as confirmed through photophysical, thioflavin assay, circular dichroism (CD), atomic force microscopy (AFM), TEM, and selected‐area electron diffraction (SAED) techniques. These results demonstrate that the squaraine dyes 1–3 under investigation act as effective protein‐labelling and destabilizing agents of the protein amyloidogenesis.

Increased oxidative stress has been postulated to contribute to the pathogenesis of autism spectrum disorder (ASD). However, reports of alterations in oxidation markers including glutathione (GSH), the major endogenous antioxidant, are indirect, coming from blood plasma level measurements and postmortem studies. Therefore we used in‐vivo 3 Tesla proton magnetic resonance spectroscopy ([1H]MRS) to directly measure GSH concentrations in the basal ganglia (BG) and the dorsomedial prefrontal cortex of 21 normally intelligent adult males with ASD and 29 controls who did not differ in age or IQ. There was no difference in brain GSH between patients and controls in either brain area; neither did GSH levels correlate with measures of clinical severity in patients. Thus [1H]MRS measures of cortical and subcortical GSH are not a biomarker for ASD in intellectually able adult men.

Augmented Beta rectangular regression models: A Bayesian perspective
Authors: Wang Jue , Luo Sheng
Published: August 2015

Mixed effects Beta regression models based on Beta distributions have been widely used to analyze longitudinal percentage or proportional data ranging between zero and one. However, Beta distributions are not flexible to extreme outliers or excessive events around tail areas, and they do not account for the presence of the boundary values zeros and ones because these values are not in the support of the Beta distributions. To address these issues, we propose a mixed effects model using Beta rectangular distribution and augment it with the probabilities of zero and one. We conduct extensive simulation studies to assess the performance of mixed effects models based on both the Beta and Beta rectangular distributions under various scenarios. The simulation studies suggest that the regression models based on Beta rectangular distributions improve the accuracy of parameter estimates in the presence of outliers and heavy tails. The proposed models are applied to the motivating Neuroprotection Exploratory Trials in Parkinson's Disease (PD) Long‐term Study‐1 (LS‐1 study,n= 1741), developed by The National Institute of Neurological Disorders and Stroke Exploratory Trials in Parkinson's Disease (NINDS NET‐PD) network.

Published: August 2015

Anchorage‐dependent cell cultures are used for the production of viruses, viral vectors, and vaccines, as well as for various cell therapies and tissue engineering applications. Most of these applications currently rely on planar technologies for the generation of biological products. However, as new cell therapy product candidates move from clinical trials towards potential commercialization, planar platforms have proven to be inadequate to meet large‐scale manufacturing demand. Therefore, a new scalable platform for culturing anchorage‐dependent cells at high cell volumetric concentrations is urgently needed. One promising solution is to grow cells on microcarriers suspended in single‐use bioreactors. Toward this goal, a novel bioreactor system utilizing an innovative Vertical‐Wheel™ technology was evaluated for its potential to support scalable cell culture process development. Two anchorage‐dependent human cell types were used: human lung carcinoma cells (A549 cell line) and human bone marrow‐derived mesenchymal stem cells (hMSC). Key hydrodynamic parameters such as power input, mixing time, Kolmogorov length scale, and shear stress were estimated. The performance of Vertical‐Wheel bioreactors (PBS‐VW) was then evaluated for A549 cell growth and oncolytic adenovirus type 5 production as well as for hMSC expansion. Regarding the first cell model, higher cell growth and number of infectious viruses per cell were achieved when compared with stirred tank (ST) bioreactors. For the hMSC model, although higher percentages of proliferative cells could be reached in the PBS‐VW compared with ST bioreactors, no significant differences in the cell volumetric concentration and expansion factor were observed. Noteworthy, the hMSC population generated in the PBS‐VW showed a significantly lower percentage of apoptotic cells as well as reduced levels of HLA‐DR positive cells. Overall, these results showed that process transfer from ST bioreactor to PBS‐VW, and scale‐up was successfully carried out for two different microcarrier‐based cell cultures. Ultimately, the data herein generated demonstrate the potential of Vertical‐Wheel bioreactors as a new scalable biomanufacturing platform for microcarrier‐based cell cultures of complex biopharmaceuticals. © 2015 American Institute of Chemical Engineers Biotechnol.

Characterization of Early Enzymes Involved in TDP‐Aminodideoxypentose Biosynthesis en Route to Indolocarbazole AT2433
Authors: Peltier‐Pain Pauline , Singh Shanteri , Thorson Jon S.
Published: August 2015

The characterization of TDP‐α‐d‐glucose dehydrogenase (AtmS8), TDP‐α‐d‐glucuronic acid decarboxylase (AtmS9), and TDP‐4‐keto‐α‐d‐xylose 2,3‐dehydratase (AtmS14), involved in Actinomadura melliaura AT2433 aminodideoxypentose biosynthesis, is reported. This study provides the first biochemical evidence that both deoxypentose and deoxyhexose biosynthetic pathways share common strategies for sugar 2,3‐dehydration/reduction and implicates the sugar nucleotide base specificity of AtmS14 as a potential mechanism for sugar nucleotide commitment to secondary metabolism. In addition, a re‐evaluation of the AtmS9 homologue involved in calicheamicin aminodeoxypentose biosynthesis (CalS9) reveals that CalS9 catalyzes UDP‐4‐keto‐α‐d‐xylose as the predominant product, rather than UDP‐α‐d‐xylose as previously reported. Cumulatively, this work provides additional fundamental insights regarding the biosynthesis of novel pentoses attached to complex bacterial secondary metabolites.

Published: August 2015

Ternary layered LiNi0.5Co0.2Mn0.3O2 microspheres are functionally surface‐modified with a fast‐Li+‐conductive Li2ZrO3‐based shell through a facile synthetic strategy based on an infiltrative pre‐coating treatment combined with a single‐step post‐sintering process. Owing to the complete nanoscale Li2ZrO3 shell coating, which has a 3D diffusion path for Li+, the resultant coated LiNi0.5Co0.2Mn0.3O2 microspheres manifest remarkably enhanced rate capability and cycling performance as cathode materials both at room and elevated temperature when tested in a half Li‐ion battery cell. Moreover, the combination of the coated LiNi0.5Co0.2Mn0.3O2 cathode and a commercial graphite anode into a full cell not only delivers a remarkable specific capacity of 140 mAh g−1 under 1 C, but also exhibits an excellent capacity retention of 78 % with a high coulombic efficiency of over 99.5 % after 100 cycles, which demonstrates its application as a promising electrochemical device for energy storage and conversion.

Authors: Feng Xian‐Juan , Prots Yurii , Bobnar Matej , Schmidt Marcus Peter , Schnelle Walter , Zhao Jing‐Tai , Grin Yuri
Published: August 2015

The compound Sr3LiAs2H was synthesized by reaction of elemental strontium, lithium, and arsenic, as well as LiH as hydrogen source. The crystal structure was determined by single‐crystal X‐ray diffraction: space group Pnma; Pearson symbol oP28; a = 12.0340(7), b = 4.4698(2), c = 12.5907(5) Å; V = 677.2(1) Å3; RF = 0.047 for 1021 reflections and with 36 parameters refined. The positions of the hydrogen atoms were first revealed by the electron localizability indicator and subsequently confirmed by crystal structure refinement. In the crystal structure of Sr3LiAs2H the metal atoms are arranged in a Gd3NiSi2‐type motif, whereas the hydrogen atoms are arranged in a distorted tetrahedral environment formed by strontium. The calculated band structure revealed that Sr3LiAs2H is a semiconductor, which is in agreement with its diamagnetic behavior. Thus, Sr3LiAs2H is considered as a (charge‐balanced) Zintl phase.
