[HTML][HTML] Entropy transfer between residue pairs and allostery in proteins: quantifying allosteric communication in ubiquitin

A Hacisuleyman, B Erman - PLoS computational biology, 2017 - journals.plos.org
It has recently been proposed by Gunasakaran et al. that allostery may be an intrinsic property
of all proteins. Here, we develop a computational method that can determine and quantify …

Prediction of allosteric communication pathways in proteins

T Haliloglu, A Hacisuleyman, B Erman - Bioinformatics, 2022 - academic.oup.com
Motivation Allostery in proteins is an essential phenomenon in biological processes. In this
article, we present a computational model to predict paths of maximum information transfer …

Causality, transfer entropy, and allosteric communication landscapes in proteins with harmonic interactions

A Hacisuleyman, B Erman - Proteins: Structure, Function, and …, 2017 - Wiley Online Library
A fast and approximate method of generating allosteric communication landscapes in
proteins is presented by using Schreiber's entropy transfer concept in combination with the …

Synchronous and asynchronous response in dynamically perturbed proteins

A Hacisuleyman, A Erkip, B Erman… - The Journal of Physical …, 2021 - ACS Publications
We present a dynamic perturbation-response model of proteins based on the Gaussian
Network Model, where a residue is perturbed periodically, and the dynamic response of other …

SARS-Cov-2 delta variant decreases nanobody binding and ACE2 blocking effectivity

M Golcuk, A Hacisuleyman, SZ Yilmaz… - Journal of Chemical …, 2022 - ACS Publications
The Delta variant spreads more rapidly than previous variants of SARS-CoV-2. This variant
comprises several mutations on the receptor-binding domain (RBD Delta ) of its spike …

Binding mechanism of neutralizing nanobodies targeting SARS-CoV-2 spike glycoprotein

M Golcuk, A Hacisuleyman, B Erman… - Journal of Chemical …, 2021 - ACS Publications
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) enters human cells upon
binding of its spike (S) glycoproteins to ACE2 receptors. Several nanobodies neutralize SARS…

Synergy and anti‐cooperativity in allostery: Molecular dynamics study of WT and oncogenic KRAS‐RGL1

A Hacisuleyman, B Erman - Proteins: Structure, Function, and …, 2023 - Wiley Online Library
This study focuses on investigating the effects of an oncogenic mutation (G12V) on the stability
and interactions within the KRAS‐RGL1 protein complex. The KRAS‐RGL1 complex is of …

ModiBodies: A computational method for modifying nanobodies in nanobody-antigen complexes to improve binding affinity and specificity

A Hacisuleyman, B Erman - Journal of Biological Physics, 2020 - Springer
Nanobodies are special derivatives of antibodies, which consist of single domain fragments.
They have become of considerable interest as next-generation biotechnological tools for …

Information flow and allosteric communication in proteins

A Hacisuleyman, B Erman - The Journal of Chemical Physics, 2022 - pubs.aip.org
Based on Schreiber’s work on transfer entropy, a molecular theory of nonlinear information
transfer between residue pairs in proteins is developed. The joint distribution function for …

Fine tuning rigid body docking results using the Dreiding force field: A computational study of 36 known nanobody‐protein complexes

A Hacisuleyman, B Erman - Proteins: Structure, Function, and …, 2023 - Wiley Online Library
