基于RNA的机器在自然界中无处不在,对医学越来越重要。它们折叠成复杂的动态结构,处理信息并催化反应,包括在生物学中产生新RNA和蛋白质的反应。了解这些复杂机器如何工作所必需的实验策略和步骤是什么?1990年Herschlag和Cech的两篇论文“Catalysis of RNA Cleavage by the Tetrahymena thermophila Ribozyme”提供了通过动力学方法解剖RNA机器的大师级课程。通过展示如何提出一个动力学框架,填写数字,进行交叉检查,并在突变体和不同的RNA系统之间进行比较,这些论文说明了如何采取机械方法并将结果提炼成通过其他手段难以获得的一般见解。
RNA-based machines are ubiquitous in Nature and increasingly important for medicines. They fold into complex, dynamic structures that process information and catalyze reactions, including reactions that generate new RNAs and proteins across biology. What are the experimental strategies and steps that are necessary to understand how these complex machines work? Two 1990 papers from Herschlag and Cech on “Catalysis of RNA Cleavage by the Tetrahymena thermophila Ribozyme” provide a master class in dissecting an RNA machine through kinetics approaches. By showing how to propose a kinetic framework, fill in the numbers, do cross-checks, and make comparisons across mutants and different RNA systems, the papers illustrate how to take a mechanistic approach and distill the results into general insights that are difficult to attain through other means.
