   <abstract xml:lang="ru">
    <p>Образование комплексов и кристаллов бактериальной нуклеоидной ДНК внутри клеток бактерий в ответ на неблагоприятные внешние воздействия представляет большой интерес как в биофизике и структурной биологии, так и в различных областях промышленности. Основную роль в конденсации и кристаллизации ДНК у бактерий в стрессовых условиях (голодание, температурный, окислительный и другие виды стресса) играют ДНК-связывающие белки DPS. В данной работе методом классической молекулярной динамики в полноатомном приближении исследуется динамическое поведение и структура комплексов белка DPS бактерии Escherichia coli в растворе с короткоцепочечной ДНК (25 пар нуклеотидов), при изменении концентрации фенольного липида 4-гексилрезорцина, являющегося химическим аналогом индукторов анабиоза бактерий. Изучается влияние изменения концентрации 4-гексилрезорцина от 0 до 50, 100 и 500 молекул на комплекс ДНК-DPS. Методом поиска линейной энергии взаимодействия получены данные о свободных энергиях связывания ДНК с белком без и в присутствии 4-гексилрезорцина. Показано, что большие концентрации 4-гексилрезорцина способствуют образованию комплексов ДНК с DPS. Для выявления особенностей динамического поведения ДНК и белка был проведён анализ главных компонент. Получены пространственные и энергетические характеристики комплексов.</p>

    <p>The formation of complexes and crystals of bacterial nucleoid DNA inside bacterial cells in response to adverse external influences is of great interest both in biophysics and structural biology, and in various fields of industry. The main role in the condensation and crystallization of DNA in bacteria under stressful conditions (starvation, temperature, oxidative, and other types of stress) is played by DNA-binding proteins DPS. In this work, the dynamic behavior and structure of Escherichia coli DPS protein complexes in solution with short-chain DNA (25 base pairs) are studied using classical molecular dynamics in the all-atom approximation with a change in the concentration of the phenolic lipid 4-hexylresorcinol, which is a chemical analog of bacterial anabiosis inducers. The effect of changing the concentration of &#13;
4-hexylresorcinol from 0 to 50, 100 and 500 molecules on the DNA-DPS complex is being studied. By searching for the linear interaction energy, data were obtained on the free energies of DNA-protein binding without and in the presence of 4-hexylresorcinol. It has been shown that high concentrations of &#13;
4-hexylresorcinol promote the formation of DNA complexes with DPS. To identify the features of the dynamic behavior of DNA and protein, the principal component analysis was carried out. The spatial and energy characteristics of the complexes was obtained.</p>
