   <abstract xml:lang="ru">
    <p>С помощью липосомальной модели установлена прямая зависимость между изменениями в молекулярной структуре неспецифических поринов наружной мембраны грамотрицательных бактерий, происходящими под действием температуры, и функциональной активностью этих белков. В работе были использованы: OmpF порин из Y. ruckeri , бактерии патогенной для рыб и в качестве белка сравнения классический OmpF порин из E. coli . Установлено, что в отличие от порина из E. coli, OmpF порин из Y. ruckeri более устойчив к действию температуры. Для обоих белков показано, что стабильное освобождение флуорометки наблюдается до температуры, не превышающей критическую температуру диссоциации тримеров белков на мономеры, при более высокой температуре наблюдается резкое снижение каналообразующей активности поринов. Высказано предположение о том, что необратимые конформационные изменения в мономерах поринов, происходящие в результате термоденатурации, «не позволяют» им образовывать проводящий тримерный канал даже в липидном окружении.</p>

    <p>Using liposome model, a direct relationship between changes in the molecular structure of the nonspecific porins of the outer membrane of Gram-negative bacteria that occur under the influence of temperature and the functional activity of these proteins has been established. OmpF porin from Y. ruckeri , bacteria pathogenic for fish and classical OmpF porin from E. coli as a comparison protein were used in the study. It was found that unlike porin from E. coli , OmpF porin from Y. ruckeri is more resistant to temperature. For both proteins, stable release of the fluorophore was observed up to a temperature not exceeding the critical temperature of the dissociation of trimers of the proteins into monomers, at a higher temperature a sharp decrease in the channel- forming activity of the porins was found. It is suggested that irreversible conformational changes in the porin monomers that occur as a result of thermal denaturation &quot;do not allow&quot; them to form a conducting trimeric channel even in a lipid environment.</p>
