Capillary assembly of microscale ellipsoidal, cuboidal, and spherical particles at interfaces

S Dasgupta, M Katava, M Faraj, T Auth, G Gompper - Langmuir, 2014 - ACS Publications
Micron-sized anisotropic particles with homogeneous surface properties at a fluid interface
can deform the interface due to their shape. The particles thereby create excess interfacial …

Critical structural fluctuations of proteins upon thermal unfolding challenge the Lindemann criterion

M Katava, G Stirnemann, M Zanatta… - Proceedings of the …, 2017 - National Acad Sciences
Internal subnanosecond timescale motions are key for the function of proteins, and are
coupled to the surrounding solvent environment. These fast fluctuations guide protein …

[PDF][PDF] Chromatin dynamics controls epigenetic domain formation

M Katava, G Shi, D Thirumalai - Biophysical Journal, 2022 - cell.com
In multicellular organisms, nucleosomes carry epigenetic information that defines distinct
patterns of gene expression, which are inherited over multiple generations. The enhanced …

Specific interactions and environment flexibility tune protein stability under extreme crowding

M Katava, G Stirnemann, M Pachetti… - The Journal of …, 2021 - ACS Publications
Macromolecular crowding influences protein mobility and stability in vivo. A precise description
of the crowding effect on protein thermal stability requires the estimate of the combined …

[HTML][HTML] Thermal activation of 'allosteric-like'large-scale motions in a eukaryotic Lactate Dehydrogenase

M Katava, M Maccarini, G Villain, A Paciaroni… - Scientific reports, 2017 - nature.com
Conformational changes occurring during the enzymatic turnover are essential for the regulation
of protein functionality. Individuating the protein regions involved in these changes and …

Stability and function at high temperature. What makes a thermophilic GTPase different from its mesophilic homologue

M Katava, M Kalimeri, G Stirnemann… - The Journal of Physical …, 2016 - ACS Publications
Comparing homologous enzymes adapted to different thermal environments aids to shed
light on their delicate stability/function trade-off. Protein mechanical rigidity was postulated to …

Temperature unmasks allosteric propensity in a thermophilic malate dehydrogenase via dewetting and collapse

M Katava, M Marchi, D Madern, M Sztucki… - The Journal of …, 2020 - ACS Publications
In this work, we combine experiments and molecular simulations to unveil the hidden allosteric
propensity of a thermophilic malate dehydrogenase protein (MDH). We provide evidence …

Configurational disorder of water hydrogen-bond network at the protein dynamical transition

O Rahaman, M Kalimeri, M Katava… - The Journal of …, 2017 - ACS Publications
We introduce a novel strategy to quantify the disorder of extended water–water hydrogen-bond
(HB) networks sampled in particle-based computer simulations. The method relies on the …

[PDF][PDF] Supplemental Information: Stability and Function at High Temperature. What Makes a Thermophilic GTPase Different from its Mesophilic Homologue.

M Katava, M Kalimeri, G Stirnemann, F Sterpone - pstorage-acs-6854636.s3 …
Table S1: Conformational and kinetic clustering of the MD simulations. The conformational
clustering was based on the collective variable RMSD and using a cut-off of 2.5 Å. The total …

[PDF][PDF] Probing the Thermal Stability of Lysozyme in Crowded Environments: Tracking Lindemann Criterion

M Katava, G Stirnemann, S Capaccioli, A Paciaroni… - Biophysical …, 2016 - cell.com
Our work focuses on determining the effect of crowded environment and different solvents
on the thermal stability of the protein Lysozyme [1] placed in a dilute water solution, …
