   <abstract xml:lang="ru">
    <p>Методом теopетического конформационного анализа исследованы конформационные возможности молекулы казоксина А (Tyr1-Pro2-Ser3-Tyr4-Gly5-Leu6-Asn7-NH2). Потенциальная функция системы выбрана в виде суммы невалентных, электростатических и торсионных взаимодействий и энергии водородных связей. Найдены низкоэнергетические конформации молекулы казоксина А, значения двугранных углов основных и боковых цепей аминокислотных остатков, входящих в состав молекулы, оценена энергия внутри- и межостаточных взаимодействий. Показано, что пространственная структура молекулы казоксина А представляется конформациями четырнадцати шейпов пептидного скелета. Полученные результаты могут быть использованы для выяснения структурной и структурно-функциональной организации молекул казоксинов.</p>

    <p>By the method of the theoretic conformational analysis the conformational capabilities of the Casoxin A molecule (Tyr1-Pro2-Ser3-Tyr4-Gly5-Leu6-Asn7-NH2) were studied. The potential function of the system is chosen as the sum of non-valent, electrostatic and torsion interactions and the energy of hydrogen bonds. Low-energy conformations of the casoxin A molecule, the values of the dihedral angles of the main and side chains of amino acid residues that make up the molecules are founded; the energy of intra- and inter-residual interactions is estimated. It is shown that the spatial structure of the casoxin A molecule can be represented by the conformations of fourteen shapes of the peptide backbone. The results obtained can be used to elucidate the structural and structural-functional organization of casoxin molecules.</p>
