We introduce a formulation for normal mode analyses of globular proteins that significantly improves on an earlier one-parameter formulation [M. M. Tirion, Phys. Rev. Lett. 77, 1905 (1996)] that characterized the slow modes associated with protein data bank structures. Here we develop that empirical potential function that is minimized at the outset to include two features essential to reproduce the eigenspectra and associated density of states in the 0 to 300cm-1 frequency range, not merely…

Slow normal modes of proteins are accurately reproduced across different platforms

It is found that the shapes of the slowest eigenvectors are nearly identical, not merely similar, and the eigenvector decomposition must be accurate, reliable as well as rapid to be generally reported upon.

Universality of vibrational spectra of globular proteins

It is shown that the density of modes of the vibrational spectrum of globular proteins is universal, i.e. regardless of the protein in question, it closely follows one universal curve. The present

Kinematic Flexibility Analysis: Hydrogen Bonding Patterns Impart a Spatial Hierarchy of Protein Motion

This work introduces a novel protein hydrogen bond network spectral decomposition, which provides an orthonormal basis for collective motions modulated by noncovalent interactions, analogous to the eigenspectrum of normal modes, and suggests that hydrogen bond networks have evolved to modulate protein structure and dynamics, which can be efficiently probed by kinematic flexibility analysis.

PDB-NMA of a protein homodimer reproduces distinct experimental motility asymmetry

The vibrational analysis of this PDB entry, together with biochemical and crystallographic data, demonstrates the cooperative nature of the dimeric interaction of the two subunits and suggests a mechanical model for subunit interconversion during the catalytic cycle.

The effective degeneracy of protein normal modes

This work investigates the nature of normal modes and finds that the normal modes of proteins, especially those at the low frequency range (0-600 cm(-1)), are highly susceptible to degeneracy, and finds the degree of degeneracy of modes is proportional to the density of modes in the vibrational spectrum.

Normal‐mode driven exploration of protein domain motions

A new approach is proposed: instead of building conformers directly with the values of a subset of normal coordinates, they are built in two steps, the conformer built with normal coordinates being just used for defining a set of distance constraints, the final conformer being built so as to match them.

Normal mode analysis calculation for a full-atom model with a smaller number of degrees of freedom for huge protein molecules

These results imply that proteins in a full-atom model can undergo only limited large-scale conformational changes around the native conformation, and consequently, NMA results do not strongly depend on the independent variables adopted.

On the sensitivity of protein data bank normal mode analysis: an application to GH10 xylanases

Protein data bank entries obtain distinct, reproducible flexibility characteristics determined by normal mode analyses of their three dimensional coordinate files, by analyzing the results on one class of glycosidases: family 10 xylanases.

A comparison of the innate flexibilities of six chains in F1-ATPase with identical secondary and tertiary folds; 3 active enzymes and 3 structural proteins

It is observed that while the foot and head regions in all chains obtain high and similar mobility, the torsos obtain different mobility profiles, with the β subunits exhibiting a higher motility compared to the α subunits, a trend supported by the crystallographic B-factors.

Modeling of Protein Structural Flexibility and Large-Scale Dynamics: Coarse-Grained Simulations and Elastic Network Models

Two alternative approaches to the coarse-grained modeling of dynamic properties of protein systems are presented, including two CG representations of polypeptide chains used for Monte Carlo dynamics simulations of protein local dynamics and conformational transitions and highly simplified structure-based elastic network models of protein flexibility.

It is shown that a single-parameter potential is sufficient to reproduce the slow dynamics of proteins obtained with vastly more complex empirical potentials, which inevitably leads to unstable modes which must be eliminated through elaborate methods, and which cast doubts on the validity of the analysis.

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.

Near-native structure refinement using in vacuo energy minimization

A powerfully convergent energy-minimization method is used and it is shown that, of the traditional molecular mechanics potentials tested, only one showed a modest net improvement over a large data set of structurally diverse proteins.

Normal mode analysis of G-actin.

A normal mode analysis of the G-actin monomer bound with ADP and Ca2+, in order to better understand the internal modes of this protein shows that the softest modes are almost identical.

Comparing the spectra of several globular proteins, it is found that the density of states follows a characteristic, universal curve, which reflects the main structural similarities between proteins.

ProMode: a database of normal mode analyses on protein molecules with a full-atom model

ProMode, a database collecting NMA results on protein molecules, was constructed and it is hoped that realistic animations of the protein dynamics can be observed easily without expensive software and hardware, and that the dynamic properties for various proteins can be compared with each other.

Anisotropic network model: systematic evaluation and a new web interface

Residue fluctuations in globular proteins are shown to be more accurately predicted than those in nonglobular proteins, and core residues are more accurately described than solvent-exposed ones.

Nonlinear elasticity, proteinquakes, and the energy landscapes of functional transitions in proteins

This work presents a model for global structural transformations, such as allostery, that involve large-scale motion and possible partial unfolding, illustrating the method with the conformational transition of adenylate kinase.
