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

AbstractEinkernige 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

Abstract1,2‐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

AbstractTechniques 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

AbstractTreatment 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

AbstractThe 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

AbstractWith 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.
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

AbstractThe 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

AbstractTernary 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.

Published: August 2015

AbstractThe 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.
