   <abstract xml:lang="ru">
    <p>Компьютерное моделирование, основанное на использование метода теоретического конформационного анализа и программ, которые позволяют получать графическое изображение пространственных структур биомолекул, было выполнено для гексапептидной молекулы – глипролина H-Phe-Gly-Gly-Phe-Gly-Pro-OH. Глипролины – это короткие пептиды, аминокислотные последовательности которых содержат остатки глицина и пролина. Механизмы их действия в настоящее время мало изучены. С помощью метода молекулярной механики было определено пространственное строение и конформационные возможности этой гексапептидной молекулы. Ее потенциальная энергия оценивалась как сумма невалентных, электростатических, торсионных взаимодействий и энергии водородных связей. Было найдено 9 низкоэнергетических структур для глипролинового гексапептида, значения двугранных углов основной и боковых цепей аминокислот, входящих в молекулу. Была оценена энергия внутри- и межостаточных взаимодействий. Расчет показал, что низкоэнергетическими для гексапептида являются свернутые формы основной цепи. В них боковые цепи аминокислот фенилаланинов и пролина, которые являются конформационно жесткими, осуществляют эффективные взаимодействия со всеми участками гексапептидной молекулы.</p>

    <p>Computer modeling based on the use of the method of theoretical conformational analysis and programs that allow obtaining a graphic image of the spatial structures of biomolecules was performed for a hexapeptide molecule – glyproline H-Phe-Gly-Gly-Phe-Gly-Pro-OH. Glyprolines are short peptides whose amino acid sequences contain glycine and proline residues. Their mechanisms of action are currently poorly understood. Using the method of molecular mechanics, the spatial structure and conformational possibilities of this hexapeptide molecule were determined. Its potential energy was estimated as the sum of non-valente, electrostatic, torsion interactions and the energy of hydrogen bonds. 9 low-energy structures were found for the glyproline hexapeptide, the values of the dihedral angles of the main and side chains of the amino acids included in the molecule. The energy of intra- and interresidual interactions was estimated. The calculation showed that the folded forms of the main chain are low-energy for the hexapeptide. In them, the side chains of amino acids phenylalanine and proline, which are conformationally rigid, carry out effective interactions with all parts of the hexapeptide molecule.</p>
