(2009)The mechanisms of the Diels-Alder (DA) reactions of 2-methoxy-5-methyl-1,4-benzoquinone 1 with 2-methyl-1,3-butadiene 2, in the absence and in the presence of LA catalysts, have been studied using the DFT method at the ...

(American Chemical Society, 2020)The existence of polycrystalline shells has been widely reported in the synthesis of hollow nanoparticles; however, the exact role displayed by the grain boundaries on the stability has been scarcely studied. By including ...
-
(MDPI, 2021)A real space understanding of the Su-Schrieffer-Heeger model of polyacetylene is introduced thanks to delocalization indices defined within the quantum theory of atoms in molecules. This approach enables to go beyond the ...
-
(Wiley, 2018)Aim: We assess biogeographical patterns, population structure and the range of species in the pulmonate genus Siphonaria across the sub-Antarctic. We hypothesized that locally endemic cryptic species will be found across ...

Unfolding pathway of the dimeric and tetrameric forms of phosphofructokinase-2 from Escherichia coli (2007)Escherichia coli phosphofructokinase-2 (Pfk-2) is an oligomeric enzyme characterized by two kinds of interfaces: a monomer-monomer interface, critical for enzymatic activity, and a dimer-dimer interface formed upon ...
-
(IOP, 2022)A unification in terms of exact solutions for massless Klein-Gordon, Dirac, Maxwell, Rarita-Schwinger, Einstein, and bosonic and fermionic fields of any spin is presented. The method is based on writing all of the relevant ...
-
(De Gruyter, 2017-01)In this paper, we study convergence characteristics of a class of continuous time fractional-order cellular neural network containing delay. Using the method of Lyapunov and Mittag-Leffler functions, we derive sufficient ...

(2010)Analyses of clone libraries from water and sediments of different sites from Salar de Huasco, a high-altitude athalassohaline wetland in the Chilean Altiplano, revealed the presence of five unique clusters of uncultured ...

(AMER PHYSIOLOGICAL SOC, 2009-03-02)Delgado R, Bacigalupo J. Unitary recordings of TRP and TRPL channels from isolated Drosophila retinal photoreceptor rhabdomeres: activation by light and lipids. J Neurophysiol 101: 2372–2379, 2009. First published March ...
-
(2000)We use the discrete nonlinear Schrödinger (DNLS) equation to show that nonlinear tight-binding lattices of different geometries and dimensionalities display a universal self-trapping behavior. First, we consider the problem ...
-
(2013)In this article the universal Poisson enveloping algebra for a binary-Lie algebra is constructed. Taking a basis B{double-struck} of a binary-Lie algebra B, we consider the symmetric algebra S(B) of polynomials in the ...
-
(2011)The scale-free and small-world properties are studied in detail for the complex earthquake networks constructed from the seismic data sets taken from California (USA), Japan, Iran and Chile. It is found that, in all these ...
-
(Elsevier, 2021)Evidence regarding protein structure and function manifest the imperative role that dynamics play in proteins, underlining reconsideration of the unanimated sequence-to-structure-to-function paradigm. Structural dynamics ...

(Oxford University Press, 2018)© The Author(s) 2018. Published by Oxford University Press on behalf of the Society for Experimental Biology. Phytoene synthase (PSY) is the first committed enzyme of the carotenoid biosynthesis pathway and the most important ...
-
(Wiley, 2018)Fluoroacetate dehalogenase is able to cleavage a carbon-fluoride bond, the strongest carbon-halogen bond in nature, in a process initiated by a S(N)2 reaction. The role of the enzyme machinery and particularly of the halogen ...
-
(MDPI, 2022)MLL3, also known as KMT2C, is a lysine mono-methyltransferase in charge of the writing of an epigenetic mark on lysine 4 from histone 3. The catalytic site of MLL3 is composed of four tyrosines, namely, Y44, Y69, Y128, and ...
-
(American Chemical Society, 2020)The mechanism and selectivity of phosphine-catalyzed [3 + 2] and [3 + 3] annulations of azomethine imines and allenoates have been computationally studied. Exploration of the potential energy surface reveals that the ...
