The coronavirus spike protein, the key entity effectuating membrane fusion, cannot exist without membraneactive
fragments. In addition to fusion peptides, among such domains are HR1 and HR2. Crucial to the spike’s
refolding and membrane fusion, they are believed to both interact with each other and bind to the membranes
that are merged. To elucidate HR2’s precise role in ...

Recent advancements in genomics, propelled by artificial intelligence, have unlocked unprecedented capabilities in interpreting genomic sequences, mitigating the need for exhaustive experimental analysis of complex, intertwined molecular processes inherent in DNA function. A significant challenge, however, resides in accurately decoding genomic sequences, which inherently involves comprehending rich contextual information dispersed across thousands of nucleotides. To ...

Lateral heterogeneity, or mosaicity, is a fundamental property inherent to cell membranes that is crucial for their functioning. While microscopic inhomogeneities (e.g. rafts) are easily detected experimentally, lipid domains with nanoscale dimensions (nanoclusters of nanodomains, NDs) resist reliable characterization by instrumental methods. In such a case, important insight can be gained via computer modeling. Here, ...

Within-host infection dynamics of Omicron dramatically differs from previous variants of SARS-CoV-2. However, little is still known about which parameters of virus-cell interplay contribute to the observed attenuated replication and pathogenicity of Omicron. Mathematical models, often expressed as systems of differential equations, are frequently employed to study the infection dynamics of various viruses. Adopting such ...

Flipons – non-B DNA conformations – have been shown to play an important role in various
genomic processes. Flipons identification and localization is difficult due to their dynamic
nature. We developed deep learning approaches to identify non-B DNA secondary structures
using available information from thousands of omics data sets. We created DeepZ models
based on CNN and RNN, and ...

Understanding fusion mechanisms employed by SARS-CoV-2 spike protein entails realistic
transmembrane domain (TMD) models, while no reliable approaches towards predicting the 3D
structure of transmembrane (TM) trimers exist. Here, we propose a comprehensive computational
framework to model the spike TMD only based on its primary structure. We performed amino acid
sequence pattern matching and compared the molecular hydrophobicity potential ...

Antibiotics (AB) resistance is a major threat to global health, thus the development of novel AB classes is urgently needed. Lantibiotics (i.e. nisin) are natural compounds that effectively control bacterial populations, yet their clinical potential is very limited. Nisin targets membrane-embedded cell wall precursor — lipid II — via capturing its pyrophosphate group (PPi), which is unlikely ...

The recently developed NMR techniques enable estimation of protein configurational entropy change from the change in the average methyl order parameters. This experimental observable, however, does not directly measure the contribution of intramolecular couplings, protein main-chain motions, or angular dynamics. Here, we carry out a self-consistent computational analysis of the impact of these missing contributions ...

In order to fully understand the microscopic origins of binding specificity between nucleic acids and proteins, it is imperative to study the dependence of the binding preferences between nucleobases and protein side chains on the properties of the environment. Here, we employ molecular dynamics simulations and umbrella sampling to derive the potentials of mean force ...

Poly(ADP-ribose) glycohydrolase (PARG) regulates cellular poly(ADP-ribose) (PAR) levels by rapidly cleaving glycosidic bonds between ADP-ribose units. PARG interacts with proliferating cell nuclear antigen (PCNA) and is strongly recruited to DNA damage sites in a PAR- and PCNA-dependent fashion. Here we identified PARG acetylation site K409 that is essential for its interaction with PCNA, its localization ...

To address the structural and dynamical consequences of amino-acid attachment at 2′- or 3′-hydroxyls of the terminal ribose in oligoribonucleotides, we have performed an extensive set of molecular dynamics simulations of model aminoacylated RNA trinucleotides. Our simulations suggest that 3′-modified trinucleotides exhibit higher solvent exposure of the aminoacylester bond and may be more susceptible to ...

Функционирование многих белков, обладающих стабильной пространственной структурой в воде, часто связано с их переносом в клетку или из нее через липидную мембрану. Помимо белков, которые преодолевают такой барьер с помощью различных вспомогательных систем (например, транслоконов, мембранных переносчиков), некоторые белки способны спонтанно внедряться в мембрану с последующим проходом и рефолдингом на противоположной стороне липидного бислоя. Наиболее ...

Изменения в структурных параметрах бислоя, в частности,локальные возмущения геометрии, подвижности липидов при встраивании небольших мембрано-активных полипептидовмогут представлять особый интерес с точки зренияконтролируемого изменения активности рецепторных систем клетки. Подобная модуляция активности показана экспериментальнона клетках, обработанных цитотоксинами[1].Однако получить детальную информацию о механизме встраивания пептида-модулятора и локальных ...

Устойчивость микроорганизмов к применяемым в клинической практике антибиотикам является серьезной проблемой медицины во всем мире. В связи с этим одной из актуальных задач современной фармакологии является поиск или дизайн новых антибактериальных веществ, свободных от бремени резистентности. Перспективными кандидатами для разработки новых лекарств являются антимикробные пептиды (АМП). Среди всего разнообразия АМП особое внимание привлекают пептиды, мишенью ...
