Nucleation and growth of amyloid fibrils

S Jalali, R Zhang, MP Haataja… - The Journal of Physical …, 2023 - ACS Publications
The formation of amyloid fibrils is a complex phenomenon that remains poorly understood at
the atomic scale. Herein, we perform extended unbiased all-atom simulations in explicit …

Using all-atom simulations in explicit solvent to study aggregation of amphipathic peptides into amyloid-like fibrils

S Jalali, Y Yang, F Mahmoudinobar, SM Singh… - Journal of Molecular …, 2022 - Elsevier
Here, we perform all-atom molecular dynamics simulations in explicit solvent to study the
aggregation of amphipathic peptides into amyloid-like fibrils. We use large simulation boxes …

GRADE: A code to determine clathrate hydrate structures

F Mahmoudinobar, CL Dias - Computer Physics Communications, 2019 - Elsevier
GRADE is an open-source software package that identifies clathrate hydrate structures
given the atomic coordinates of oxygen atoms of water. These structures are commonly …

Unifying microscopic mechanism for pressure and cold denaturations of proteins

CL Dias - Physical review letters, 2012 - APS
We study the stability of globular proteins as a function of temperature and pressure through
NPT simulations of a coarse-grained model. We reproduce the elliptical stability of proteins …

Hydrophobic interactions and hydrogen bonds in β-sheet formation

C Narayanan, CL Dias - The journal of chemical physics, 2013 - pubs.aip.org
In this study, we investigate interactions of extended conformations of homodimeric peptides
made of small (glycine or alanine) and large hydrophobic (valine or leucine) sidechains …

Hierarchy of anomalies in the simple rose model of water

P Ogrin, T Urbic - Journal of Molecular Liquids, 2023 - Elsevier
The density, diffusion, and structural anomalies of the simple two-dimensional model of
water were determined by Monte Carlo simulations. The rose model was used which is a …

Thermodynamic and structural signatures of water-driven methane-methane attraction in coarse-grained mW water

B Song, V Molinero - The Journal of chemical physics, 2013 - pubs.aip.org
Hydrophobic interactions are responsible for water-driven processes such as protein folding
and self-assembly of biomolecules. Microscopic theories and molecular simulations have …

Integral equation study of the effects of rotational degrees of freedom on properties of the Mercedes–Benz water model

P Ogrin, T Urbic - Journal of Molecular Liquids, 2021 - Elsevier
We developed an analytical theory for studying of rotational degrees of freedom of a simple
model of liquid water. Wertheim's integral equation theory (IET) for associative liquids was …

Factors promoting the formation of clathrate-like ordering of water in biomolecular structure at ambient temperature and pressure

S Parui, B Jana - The Journal of Physical Chemistry B, 2019 - ACS Publications
Clathrate hydrate forms when a hydrophobic molecule is entrapped inside a water cage or
cavity. Although biomolecular structures also have hydrophobic patches, clathrate-like water …

Statistical-mechanical liquid theories reproduce anomalous thermodynamic properties of explicit two-dimensional water models

P Ogrin, T Urbic, CJ Fennell - Physical Review E, 2022 - APS
We have developed an analytical theory for a simple model of liquid water. We apply
Wertheim's thermodynamic perturbation theory (TPT) and integral equation theory (IET) for …
