   <abstract xml:lang="ru">
    <p>Размер линейных молекул пептидной природы может рассматриваться как число содержащихся в них аминокислотных остатков ( р ). Целью работы был анализ области существования и встречаемости различных природных пептидных структур с различной величиной р . В работе использовались данные базы SwissProt о более чем 5,6·105 первичных структурах, определенных полностью (sequence complete). Из них нами были удалены структуры, содержащие нестандартные аминокислотные остатки, а также идентичные копии аминокислотных последовательностей. В результате для анализа использовано 463450 различных последовательностей длиной 2 до 35213 аминокислотных остатков. Анализ показал, что у разных биологических доменов и царств число встречающихся пептидных структур на шкале р характеризуются разными областями существования, а формы профилей полученных кривых близки к ряду известных распределений. В то же время у них могут наблюдаться острые высокие пики, свидетельствующие о наличии большого количества специфических белков с одинаковой величиной р . Таким образом продемонстрировано существование множества разных первичных структур белков одинаковой длины, обладающих одинаковыми функциями. Рассмотрены возможные причины особенностей полученных распределений.</p>

    <p>The size of linear peptide molecules is considered as a number of amino acid residues ( p ) contained in them. The aim of this work was to analyze the region of existence and occurrence of various natural peptide structures with different p -values. We used SwissProt database contained more than 560000 complete primary structures. We have removed structures containing non-standard amino acid residues, as well as identical amino acid sequences. As a result, 463450 different sequences with a length of 2 to 35,213 amino acid residues were obtained for analysis. The analysis showed that the number of peptide structures on p -scale is characterized by different areas of existence in different biological domains and kingdoms, and the shapes of the profiles of the curves obtained are close to classical distributions. However, they can have sharp high peaks, indicating the presence of a large number of specific proteins with the same p -value. Possible reasons for the existence and features of such distributions are considered.</p>
