RNA解旋酶是真核生物RNA代谢中最大的一类酶。在细胞中,蛋白质辅因子调节RNA解旋酶功能并影响生化解旋酶活性。因此,了解辅因子如何影响RNA解旋酶的酶活性对于描绘细胞中RNA解旋酶的物理作用和调节至关重要。在这里,我们讨论的方法和概念上的考虑,为设计的实验,询问辅因子对RNA解旋酶活性在体外的影响。我们概述了解旋酶反应的机制框架,讨论了优化的实验设置和反应参数测量辅因子对RNA解旋酶活性的影响,并提供基本的指导数据分析和解释。所描述的方法对于确定RNA解旋酶的小分子抑制剂的影响也是有益的。
RNA helicases are the largest class of enzymes in eukaryotic RNA metabolism. In cells, protein cofactors regulate RNA helicase functions and impact biochemical helicase activities. Understanding how cofactors affect enzymatic activities of RNA helicases is thus critical for delineating physical roles and regulation of RNA helicases in cells. Here, we discuss approaches and conceptual considerations for the design of experiments to interrogate cofactor effects on RNA helicase activities in vitro. We outline the mechanistic frame for helicase reactions, discuss optimization of experimental setup and reaction parameters for measuring cofactor effects on RNA helicase activities, and provide basic guides to data analysis and interpretation. The described approaches are also instructive for determining the impact of small molecule inhibitors of RNA helicases.
