A Diels–Alder Reaction Triggered by a [4 + 3] Metallacycloaddition

Jun 26, 2015 | Artículos del Mes

The TpMe2Ir(III) complex 1-OH2 (TpMe2 = hydrotris(3,5-dimethylpyrazolyl)borate), which contains a labile molecule of water and an iridium-bonded alkenyl moiety (−C(R)═C(R)–(R=CO2Me)) as part of a benzo-annulated five-membered iridacycle, reacts readily with the...

Spatial Fluctuations in Expression of the Heterocyst Differentiation Regulatory Gene hetR in Anabaena Filaments

May 26, 2015 | Artículos del Mes, Artículos del Mes, Artículos del Mes, Artículos del Mes, Artículos del Mes

Under nitrogen deprivation, filaments of the cyanobacterium Anabaena undergo a process of development, resulting in a one-dimensional pattern of nitrogen-fixing heterocysts separated by about ten photosynthetic vegetative cells. Many aspects of gene expression before...

Langerin–Heparin Interaction: Two Binding Sites for Small and Large Ligands As Revealed by a Combination of NMR Spectroscopy and Cross-Linking Mapping Experiments

Abr 26, 2015 | 2015, 2015, 2015, 2015, 2015, 2015

Langerin is a C-type lectin present on Langerhans cells that mediates capture of pathogens in a carbohydrate-dependent manner, leading to subsequent internalization and elimination in the cellular organelles called Birbeck granules. This mechanism mediated by langerin...

Respiratory Complexes III and IV Can Each Bind Two Molecules of Cytochrome c at Low Ionic Strength

Feb 26, 2015 | Sin categoría

The transient interactions of respiratory cytochrome c with complexes III and IV is herein investigated by using heterologous proteins, namely human cytochrome c, the soluble domain of plant cytochrome c1 and bovine cytochrome c oxidase. The binding molecular...

Optical description of mesostructured organic−inorganic halide perovskite solar cells

Ene 26, 2015 | Sin categoría

Herein we describe both theoretically and experimentally the optical response of solution-processed organic-inorganic halide perovskite solar cells based on mesostructured scaffolds. We develop a rigorous theoretical model using a method based on the propagation of...
