RNA世界理论包含了一个假设,即复杂的核酶和核糖开关是古代生物体代谢过程的主要驱动力。几种类型的催化RNA和许多类别的配体传感RNA开关仍然存在于现代细胞中。奇怪的是,由RNA酶和RNA开关元件合并形成的变构核酶在今天的生物系统中基本上不存在。这是真的,尽管各种类型的自切割核酶和核糖开关适体惊人的丰度。在这里,我们提出了已知类型的配体控制的核酶和核糖开关,并讨论了可能的原因,融合的核酶-适体结构已通过进化不利。
The RNA World theory encompasses the hypothesis that sophisticated ribozymes and riboswitches were the primary drivers of metabolic processes in ancient organisms. Several types of catalytic RNAs and many classes of ligand-sensing RNA switches still exist in modern cells. Curiously, allosteric ribozyme formed by the merger of RNA enzyme and RNA switch components are largely absent in today’s biological systems. This is true despite the striking abundances of various classes of both self-cleaving ribozymes and riboswitch aptamers. Herein we present the known types of ligand-controlled ribozymes and riboswitches and discuss the possible reasons why fused ribozyme-aptamer constructs have been disfavored through evolution.
