ЧТО ОЗНАЧАЕТ СЛОВО RIBOZYME
рибозима
Рибозим представляет собой молекулу РНК, которая способна катализировать специфические биохимические реакции, аналогичные действию белковых ферментов. Открытие рибозимов в 1982 году показало, что РНК может быть как генетическим материалом, так и биологическим катализатором, и способствовала гипотезе мира РНК, которая предполагает, что РНК, возможно, была важной в эволюции пребиотических самовоспроизводящихся систем. Также называемая каталитическая РНК, рибозимы функционируют внутри рибосомы для связывания аминокислот во время синтеза белка и в различных реакциях по обработке РНК, включая сплайсинг РНК, репликацию вируса и биосинтез переноса РНК. Примеры рибозимов включают рибозим молотковой головки, VS-рибозим VS и рибозим шпильки. Исследователи, изучающие происхождение жизни, создали в лаборатории рибозимы, способные катализировать свой синтез в очень специфических условиях, таких как рибозим РНК-полимеразы. Был проведен мутагенез и селекция, в результате чего были выделены улучшенные варианты рибозима «Round-18» полимеразы с 2001 года ». B6.
