Critical Theory of Two-Dimensional Mott Transition: Integrability and Hilbert Space Mapping
(Scientific Research Publishing, 2015-04)
We reconsider the Mott transition in the context of a two-dimensional fermion model with density-density coupling. We exhibit a Hilbert space mapping between the original model and the Double Lattice Chern-Simons theory ...
Conformational pathways of simple six-membered rings
(John Wiley & Sons Ltd, 2010-12)
The conformational equilibria of cyclohexane (as well as its fluoro-, chloro-, methyl-, hydroxy-, and t-butyl derivatives), cyclohexanone, piperidine, tetrahydropyran (and its 2-hydroxy derivative) were studied by ab initio ...
E2→E1 transition and Rb+ release induced by Na+ in the Na+/K+-ATPase. Vanadate as a tool to investigate the interaction between Rb+ and E2
(Elsevier Science, 2012-09)
This work presents a detailed kinetic study that shows the coupling between the E2→E1 transition and Rb+ deocclusion stimulated by Na+ in pig-kidney purified Na,K-ATPase. Using rapid mixing techniques, we measured in ...
Electron transfer and conformational transitions of cytochrome c are modulated by the same dynamical features
(Elsevier Science Inc., 2020-02)
Cytochrome c is a prototypical multifunctional protein that is implicated in a variety of processes that are essential both for sustaining and for terminating cellular life. Typically, alternative functions other than ...
Large scale analysis of protein conformational transitions from aqueous to non-aqueous media
(BioMed Central, 2018-01)
Background: Biocatalysis in organic solvents is nowadays a common practice with a large potential in Biotechnology. Several studies report that proteins which are co-crystallized or soaked in organic solvents preserve their ...
TD-DFT calculations of UV absorption bands and their intensities in the spectra of some tetrahydroquinolines
(Royal Society of Chemistry, 2015-03-04)
A detailed analysis of the MOs involved in electronic transitions in UV spectra as well as a conformational study of 1-benzenesulfonyl-1,2,3,4-tetrahydroquinoline (BSTHQs) derivatives have been carried out using the TD-DFT ...
Exploring the conformational transition between the fully folded and locally unfolded substates of: Escherichia coli thiol peroxidase
(Royal Society of Chemistry, 2020-05)
Thiol peroxidase from Escherichia coli (EcTPx) is a peroxiredoxin that catalyzes the reduction of different hydroperoxides. During the catalytic cycle of EcTPx, the peroxidatic cysteine (CP) is oxidized to a sulfenic acid ...
Dynamic lipid-protein stoichiometry on E1 and E2 conformations of the Na+/K+-ATPase
(Elsevier Science, 2011-04)
Highlights: Intramembrane segments of Na+/K+-ATPase were labeled with [125I]TID-PC/16. E1-E2 transition is accompanied by changes in the number of annular lipids. © 2011 Federation of European Biochemical Societies. Published ...
Exploring conformational space with thermal fluctuations obtained by normal-mode analysis
(American Chemical Society, 2020-06)
Proteins in their native states can be represented as ensembles of conformers in dynamical equilibrium. Thermal fluctuations are responsible for transitions between these conformers. Normal-modes analysis (NMA) using elastic ...
Chemical potential driven phase transition of black holes in anti-de Sitter space
(American Physical Society, 2015-11)
Einstein-Maxwell theory conformally coupled to a scalar field in D dimensions may exhibit a phase transition at low temperature whose end point is an asymptotically anti-de Sitter black hole with a scalar field profile ...
