  author={Masatake Sugita and Fumio Hirata},
  journal={Journal of computational chemistry},
A new theoretical method, referred to as Generalized Langevin Mode Analysis (GLMA), is proposed to analyze the mode of structural fluctuations of a biomolecule in solution. The method combines the two theories in the statistical mechanics, or the Generalized Langevin theory and the RISM/3D-RISM theory, to calculate the second derivative, or the Hessian matrix, of the free energy surface of a biomolecule in aqueous solution, which consists of the intramolecular interaction among atoms in the…

A theory of chemical Reactions in biomolecules in solution: generalized Langevin mode analysis (GLMA)

The generalized Langevin mode analysis (GLMA) is applied to chemical reactions in biomolecules in solution. The theory sees a chemical reaction in solution as a barrier crossing process, similar to



Structural fluctuation of protein in water around its native state: a new statistical mechanics formulation.

A new statistical mechanics formulation of characterizing the structural fluctuation of protein correlated with that of water is presented based on the generalized Langevin equation and the 3D-reference interaction site model (RISM)/RISM theory of molecular liquids, which contains the variance-covariance matrix as the "Hessian" term describing the "force" restoring an equilibrium conformation.

The analysis demonstrates that, in spite of the anharmonic contributions to the potential, a normal mode description can provide useful results concerning the internal motions of proteins.

Identification of slow relaxation modes in a protein trimer via positive definite relaxation mode analysis.

This paper proposes a simple and effective extension of the RMA method, referred to as the positive definite R MA method, to introduce the evolution time parameter robustly, and demonstrates the effectiveness of the method.

Langevin modes of macromolecules

The standard gas phase normal mode analysis is generalized to condensed phases within the framework of the classical Langevin equation. The solution of this equation for a system of 3N atoms moving

Dynamic heterogeneity in the folding/unfolding transitions of FiP35.

A simple approach is proposed which uses a time correlation function matrix and applies to the folding/unfolding trajectory of FiP35 WW domain to reconcile the conflicting interpretations of the folding mechanism and highlight the complexity in the folding dynamics.

Transient conformational fluctuation of TePixD during a reaction

This is the first report showing enhanced fluctuations of intermediate species during a protein reaction, supporting the importance of fluctuations and indicates that the TePixD decamer cannot react when its structural fluctuation is small.

Signatures of Solvation Thermodynamics in Spectra of Intermolecular Vibrations

This study uses a spatially resolved extension of the two-phase thermodynamics method to estimate hydration water entropies based on the local vibrational density of states (3D-2PT), which provides unique microscopic details regarding the hydration of hydrophobic and hydrophilic functional groups.

A new method to determine electrostatic potential around a macromolecule in solution from molecular wave functions

A new procedure to save the computational cost for calculating the electrostatic potential and the solvated fock matrix is proposed and the electronic structure and the energy gradient of Methionine‐Enkephalin and solvation structure are estimated by using this procedure in aqueous solution, and are compared with the results from other procedures.

The Allostery Landscape: Quantifying Thermodynamic Couplings in Biomolecular Systems

A statistical mechanical approach is used to show that the allosteric coupling between two collective variables is not a single number, but instead a two-dimensional thermodynamic coupling function that is directly related to the mutual information from information theory and the copula density function from probability theory.
