   <abstract xml:lang="ru">
    <p>В работе методом молекулярной механики в приближении атом-атомных потенциальных функций исследовано пространственное строение и конформационные свойства нейропептида из семейства аллатостатинов, получившего название [Hyp2]Met-галлатостатина. Исследования основывались на минимизации энергии внутримолекулярных взаимодействий (невалентных, электростатических, торсионных) в окрестностях углов внутреннего вращения, соответствующих всем комбинациям стабильных конформаций монопептидных остатков, образующих молекулу. Установлены десять энергетически стабильных конформаций нейропептида, реализуемых в условиях неявно заданного водного окружения, относительная конформационная энергия которых варьирует в интервале значений 0-10 ккал/моль. Показано, система водородных связей, несмотря на небольшой вклад в общую энергию молекулы, весьма важна для сохранения устойчивой структуры и ограничения подвижности [Hyp2]Met-галлатостатин. Согласно результатам исследования, основной вклад в стабилизацию низкоэнергетических конформаций молекулы вносят невалентные взаимодействия.</p>

    <p>In work by the method of molecular mechanics in approximation of atom-atom potential functions is studied the spatial structure and conformational properties of the neuropeptide from allatostatin family, got the name of [Hyp2]Met-callatostatin. The researches were based on minimizing of the energy of intramolecular interactions ( non- bonded, electrostatic, torsion ) in the vicinity of the internal rotation angles corresponding to all combinations of stable conformations of monopeptide residues forming a molecule. There determined ten energetically stable conformations of neuropeptide, implemented under the conditions of implicitly given aqueous environment , the relative conformational energy of which varies in the range of 0-10 kcal / mol. It was shown that the system of hydrogen bonds, despite a small contribution to the total energy of the molecule is essential for the preservation of a stable structure and restriction of [Hyp2]Met-callatostatin . According to the research results, the main contribution to the stabilization of low-energy conformations of the molecule are made by non - valentinteractions.</p>
