Abstract
Twister RNAs represent a recently discovered class of natural ribozymes that promote rapid cleaving of RNA backbones. Although an abundance of theoretical, biochemical, and structural data exist for several members of the twister class, disagreements about the architecture and mechanism of its active site have emerged. Historically, such storms regarding mechanistic details typically occur soon after each new self-cleaving ribozyme class is reported, but paths forward exist to quickly reach calmer conditions.
摘要
Twister RNA代表了一类最近发现的天然核酶，可促进RNA主链的快速切割。尽管针对Twister类的几个成员已有大量的理论、生化和结构数据，但关于其活性位点的结构和机制仍存在分歧。从历史上看，每当报道一种新的自我切割核酶类时，关于其机制细节的这类争议通常很快就会出现，但也有办法能迅速达成更稳定的局面。
