Intrinsically disordered proteins: ensembles at the limits of Anfinsen's dogma

P Kulkarni, VBP Leite, S Roy, S Bhattacharyya… - Biophysics …, 2022 - pubs.aip.org
Intrinsically disordered proteins (IDPs) are proteins that lack rigid 3D structure. Hence, they
are often misconceived to present a challenge to Anfinsen's dogma. However, IDPs exist as …

Coordinate and time-dependent diffusion dynamics in protein folding

RJ Oliveira, PC Whitford, J Chahine, VBP Leite, J Wang - Methods, 2010 - Elsevier
We developed both analytical and simulation methods to explore the diffusion dynamics in
protein folding. We found the diffusion as a quantitative measure of escape from local traps …

Configuration-dependent diffusion can shift the kinetic transition state and barrier height of protein folding

J Chahine, RJ Oliveira, VBP Leite… - Proceedings of the …, 2007 - National Acad Sciences
We show that diffusion can play an important role in protein-folding kinetics. We explicitly
calculate the diffusion coefficient of protein folding in a lattice model. We found that diffusion …

Protein conformational dynamics and phenotypic switching

…, S Bhattacharya, MK Jolly, S Kotnala, VBP Leite… - Biophysical …, 2021 - Springer
Intrinsically disordered proteins (IDPs) are proteins that lack rigid 3D structure but exist as
conformational ensembles. Because of their structural plasticity, they can interact with multiple …

Topography of funneled landscapes determines the thermodynamics and kinetics of protein folding

…, E Wang, JN Onuchic, VBP Leite - Proceedings of the …, 2012 - National Acad Sciences
The energy landscape approach has played a fundamental role in advancing our understanding
of protein folding. Here, we quantify protein folding energy landscapes by exploring the …

Characterizing the Folding Transition-State Ensembles in the Energy Landscape of an RNA Tetraloop

…, FV Paulovich, AE Garcia, VBP Leite - Journal of Chemical …, 2023 - ACS Publications
Molecular dynamics (MD) simulations have become increasingly powerful and can now
describe the folding/unfolding of small biomolecules in atomic detail. However, a major …

Examining the ensembles of amyloid-β monomer variants and their propensities to form fibers using an energy landscape visualization method

…, PG Wolynes, JN Onuchic, VBP Leite - The Journal of …, 2021 - ACS Publications
The amyloid-β (Aβ) monomer, an intrinsically disordered peptide, is produced by the cleavage
of the amyloid precursor protein, leading to Aβ-40 and Aβ-42 as major products. These …

Exploring energy landscapes of intrinsically disordered proteins: Insights into functional mechanisms

…, P Kulkarni, JN Onuchic, S Roy, VBP Leite - Journal of Chemical …, 2021 - ACS Publications
Intrinsically disordered proteins (IDPs) lack a rigid three-dimensional structure and populate
a polymorphic ensemble of conformations. Because of the lack of a reference conformation, …

[PDF][PDF] Capturing transition paths and transition states for conformational rearrangements in the ribosome

JK Noel, J Chahine, VBP Leite, PC Whitford - Biophysical journal, 2014 - cell.com
To reveal the molecular determinants of biological function, one seeks to characterize the
interactions that are formed in conformational and chemical transition states. In other words, …

Unveiling Metastable Ensembles of GRB2 and the Relevance of Interdomain Communication during Folding

…, MN Sanches, GC Moreira, VBP Leite… - Journal of Chemical …, 2023 - ACS Publications
The folding process of multidomain proteins is a highly intricate phenomenon involving the
assembly of distinct domains into a functional three-dimensional structure. During this process…
