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 ...

Детальный анализ меняющихся во времени свойств молекулярных поверхностей играет важную роль в процессах распознавания, взаимодействия и передачи сигналов в биомолекулярных системах. Технология «динамического молекулярного портрета» представляет собой современный подход к расчету, наглядной визуализации и сравнительному анализу различных физико-химических характеристик поверхности биомолекул. Эффективное использование таких подходов требует создания специальных методов компьютерной обработки, анализа и представления «молекулярных ...

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 ...

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 ...

Появившиеся в распоряжении исследователей модели пространственной структуры высокого разрешения сложных надмолекулярных белок-мембранных и др. систем, наряду с результатами их атомистического компьютерного моделирования, выявили существование целого ряда своеобразных «аномальных зон» в таких объектах. В настоящей работе на основании результатов вычислительныхэкспериментов проведен анализ физико-химических и динамических свойств молекулярных систем в указанных областях. Показано, что свойства последних могут ...

Bitopic proteins having only one helical transmembrane (TM) domain are a class of biologically significant membrane proteins, including the type I receptors and amyloid precursor protein (APP), which are involved in regulating the homeostasis of human organism and recognized as substrate by c-secretase. Amyloid Ab-peptides forming plaques in brain during Alzheimer disease (AD) are the ...

Elastin is an essential component of numerous human tissues and plays a critical role in elasticity of skin, lungs and arteries. During vascular aging, the elastin network is degraded generating elastin-derived peptides (EDP). The ERC (Elastin Receptor Complex) is a membrane heterotrimeric receptor composed, amongst others, of a membrane-bound neuraminidase, NEU-1. Binding of EDP to ...

The worldwide rapid emergence of resistant bacteria put at threat the efficacy of antibiotics, thus the development of novel antibacterial agents is urgently needed. The cell wall precursor lipid II consisting the chemically conservative pyrophosphate group represents a promising pharmaceutical target. Antimicrobial peptides, that target lipid II, i.e. lantibiotic nisin, could be excellent prototypes for ...

Receptor tyrosine kinases (RTK) are vital players in cell signaling governing growth and proliferation. These integral membrane proteins work only in dimeric states, so the conformation of transmembrane dimer determines the signal transferred into cell. Here, we used modern molecular modeling techniques to study details of protein-protein and protein-lipid interactions in model systems containing monomers ...

Insulin receptor (IR) family is represented by three membrane proteins participating in organism development, growth, and vital activity. Modulation of the functioning of these receptors by external agents looks very perspective from a pharmaceutical point of view. Although IR is well studied, little is known about the role of its transmembrane (TM) domain in receptor ...

Acid-sensing ion channels (ASICs), members of the family of
amiloride-sensitive degenerin/epithelial
Na + -channels, are expressed in neurons of both the peripheral and central nervous
system. Among six currently known isoforms of mammalian
ASICs, two, namely ASIC1a and ASIC3 are widespread and
have the largest physiological contribution such as synaptic plasticity, learning and memory as well as pain perception and
inflammation ...

The human epidermal growth factor (EGFR/HER) and growth hormone (GHR) receptors serve as excellent models of type I receptors to illustrate how ligand-induced conformational rearrangements and specific dimerization of extracellular domains lead to the allosteric activation of the cytoplasmic domains via single-span transmembrane domain (TMD). We determined the alternative dimeric conformations of the EGFR and ...

Atomistic aspects of the structural organization, dynamics, and functioning of hydrated lipid bilayers - model cell membranes - are primarily governed by the fine balance of intermolecular interactions between all constituents of these systems. Besides the hydrophobic effect, which shapes the overall skeleton of lipid membranes, very important contribution to their behavior is made by ...

The growing problem of antibiotic resistance in medicine raises the attention to antimicrobial substances that act on non-protein molecules, which have more conservative structure comparing to proteins or peptides. One of the most promising and studied targets is lipid II — the participant of the bacterial cell wall biosynthetic pathway. Lipid II is present in ...

Structure, dynamics, and functioning of hydrated lipid bilayers - model cell
membranes - are governed by a thin balance of intermolecular interactions between
constituents of these systems. Besides the hydrophobic effect, which determines
the overall bilayer skeleton, important contribution is made by Hbonds
between lipids, water, and ions. This determines crucial phenomena in
cell membranes: dynamic clustering, hydration, fine tuning ...
