    Mechanistic insight into the functional transition of the enzyme guanylate kinase induced by a single mutation

    Dramatic functional changes of enzyme usually require scores of alterations in amino acid sequence. However, in the case of guanylate kinase (GK), the functional novelty is induced by a single (S→P) mutation, ...

    Theoretical Studies on the Folding Mechanisms for Different DNA G-quadruplexes

    The G-quadruplex DNA formed by the stack of guanines in human telomere sequence is a promising anticancer target. In this study we used the energy landscape theory to elucidate the folding mechanisms for the t...

    Folding Mechanisms of Trefoil Knot Proteins Studied by Molecular Dynamics Simulations and Go-model

    Most proteins need to avoid the complex topologies when folding into the native structures, but some proteins with nontrivial topologies have been found in nature. Here we used protein unfolding simulations un...

    Coarse-grained simulations for organic molecular liquids based on Gay-Berne and electric multipole potentials

    Coarse-grained studies of CH3SH, CH3CHO and CHCl3 liquids, based on anisotropic Gay-Berne (GB) and electric multipole potentials (EMP), demonstrate that the coarse-grained model is able to qualitatively reproduce...

    Observations on the JWKB treatment of the quadratic barrier

    Historically, the “lowest-order” JWKB “parabolic” connection formula between the left and right classically allowed regions for tunneling through a parabolic barrier involved a rather non-JWKB-like square-root ...
