Variants of the gain domain of adhesion g protein-coupled receptors

Patrick Daniel Barth, Matthieu François Marfoglia, Louis Georges Baptiste Dumas

The present invention relates to variants of the GAIN domain (G-protein-coupled receptor autoproteolysis-inducing domain) of an adhesion G protein-coupled receptor (ADGRG), such as a GAIN domain variant comprising or consisting of the amino acid sequence o ...

Analysis of a bac operon-silenced strain suggests pleiotropic effects of bacilysin in Bacillus subtilis

Mustafa Demir

Bacilysin, as the simplest peptide antibiotic made up of only L-alanine and L-anticapsin, is produced and excreted by Bacillus subtilis under the control of quorum sensing. We analyzed bacilysin-nonproducing strain OGU1 which was obtained by bacA-targeted ...

Assessment of metabolic fluxes in the mouse brain in vivo using (1)H-[(13)C] NMR spectroscopy at 14.1 Tesla

Rolf Gruetter, Lijing Xin, Hongxia Lei, Bernard Lanz

(13)C magnetic resonance spectroscopy (MRS) combined with the administration of (13)C labeled substrates uniquely allows to measure metabolic fluxes in vivo in the brain of humans and rats. The extension to mouse models may provide exclusive prospect for t ...

Hyperpolarized 13C lactate as a substrate for in vivo metabolic studies in skeletal muscle

Rolf Gruetter, Arnaud Comment, Josefina Adriana Maria Bastiaansen, Hikari Ananda Infinity Yoshihara, Yuhei Takado

Resting skeletal muscle has a preference for the oxidation of lipids compared to carbohydrates and a shift towards carbohydrate oxidation is observed with increasing exercise. Lactate is not only an end product in skeletal muscle but also an important meta ...

Reaction Mechanism and Catalytic Fingerprint of Allantoin Racemase

Matteo Dal Peraro, Marco Stenta, Matteo Thomas Degiacomi, Thomas Lemmin, Christophe Bovigny

The stereospecific oxidative decomposition of urate into allantoin is the core of purine catabolism in many organisms. The spontaneous decomposition of upstream intermediates and the nonenzymatic racemization of allantoin lead to an accumulation of (R)-all ...

Synthesis of Iminonitriles by Oxone/TBAB-Mediated One-Pot Oxidative Three-Component Strecker Reaction

Jieping Zhu, Qian Wang, Jean-Baptiste Gualtierotti

Oxidative three-component reaction of aldehydes, amines, and TMSCN in a biphasic solvent system (toluene/H2O) containing Oxone, tetra-n-butylammonium bromide (TBAB) and sodium bicarbonate afforded α-iminonitriles in good to excellent yields. This oxidative ...

Amidation of Aldehydes and Alcohols through α-Iminonitriles and a Sequential Oxidative Three-Component Strecker Reaction/Thio-Michael Addition/Alumina-Promoted Hydrolysis Process to Access β-Mercaptoamides from Aldehydes, Amines, and Thiols

Jieping Zhu, Qian Wang, Jean-Baptiste Gualtierotti

Mild and general alumina promoted hydrolysis conditions for converting α-iminonitriles into carboxamides have been developed. In combination with the oxidative three-component Strecker reaction, the one-pot direct amidation of aldehydes and alcohols is rep ...

Structural evolution of amino acid crystals under stress from a non-empirical density functional

Riccardo Sabatini

Use of the non-local correlation functional vdW-DF (from 'van der Waals density functional'; Dion M et al 2004 Phys. Rev. Lett. 92 246401) has become a popular approach for including van der Waals interactions within density functional theory. In this work ...

Neuroprotective role of lactate after cerebral ischemia

Rolf Gruetter, Pierre Magistretti, Hongxia Lei

It is well established that lactate can be used as an energy substrate by the brain by conversion to pyruvate and a subsequent oxidation in the mitochondria. Knowing the need for readily metabolizable substrates directly after ischemia and the protective e ...
