   <abstract xml:lang="ru">
    <p>Поиск возможностей управлять образованием амилоидных белковых фибрилл является целью многих исследований. Для остановки и инициации процесса роста амилоидных фибрилл А-бета пептида на его основе были спроектированы мутантные пептиды, несущие замены аминокислотных остатков в ключевых положениях на пролин. Для исследования механизма действия этих пептидов была спроектирована гибридная конструкция в основе которой лежит термостабильный гексамерный белок Hfq к которому присоединены амилоидогенные пептиды. Эта конструкция была получена, выделена и очищена. Была протестирована стабильность и способность к агрегации при нагревании. Результаты экспериментов подтверждают предположения высокой стабильности и стойкости к агрегации полученной конструкции по сравнению с гибридным белком на основе тиоредоксина, который использовался ранее. Эти результаты позволят использовать разработанную конструкцию в исследованиях амилоидообразования.</p>

    <p>The search for ability to manage the formation of amyloid fibrils is the goal of many studies. To stop and initiate the growth process of amyloid fibrils of the A-beta peptide, mutant peptides with key amino acid substitutions to proline were designed. To investigate the mechanism of action of these peptides, a hybrid construction based on the thermostable hexameric Hfq protein to which these peptides are attached was designed. This fusion protein was obtained, isolated and purified. Its stability and ability to aggregate on heating was tested. The results of the experiments confirm the hypotheses of high stability and resistance to aggregation of the obtained structure in comparison with the thioredoxin-based hybrid protein that was used previously. These results will allow us to use the developed design in studies of amyloid formation.</p>
