核糖开关的发现和表征已经走了很长的路,因为这个词是在近二十年前首次创造的。核糖开关本身很可能来自古老的配体结合转录本,这些转录本已经进化成广泛存在于原核生物中的复杂遗传控制元件。核糖开关与许多细胞过程相关,包括生物合成途径,运输机制和应激反应,从而导致对其触发和功能的深入了解,以解决生理和调节问题。大多数核糖开关通过转录或翻译表达平台发挥其控制作用,这取决于其遗传背景。然而,仍有待确定的是,为什么一个平台比另一个平台更受青睐。这是基因表达机制的布局、配体的可用性、所需的控制程度、偶然发现还是这些因素的各种组合的问题?通过这篇评论,而不是提供答案,我希望为关于这个难题的进一步科学讨论播下种子。
Riboswitch discovery and characterisation have come a long way since the term was first coined almost two decades ago. Riboswitches themselves are likely derived from ancient ligand-binding transcripts, which have evolved into sophisticated genetic control elements that are widespread in prokaryotes. Riboswitches are associated with a multitude of cellular processes including biosynthetic pathways, transport mechanisms and stress responses leading to an ever-increasing appreciation for an in-depth understanding of their triggers and functions in order to address physiological and regulatory questions. The majority of riboswitches exert their control via transcriptional or translational expression platforms depending on their genetic context. It remains, however, to be determined precisely why one platform is favoured over another. Is this a question of the layout of the gene expression machinery, ligand availability, the degree of control required, serendipity or various combinations of these? With this review, rather than providing answers, I am hoping to plant a seed for further scientific discussions about this puzzle.
