细菌利用一系列统称为小RNA(SRNAs)的RNA调节器来帮助响应环境的变化。许多sRNA通过有限的碱基配对相互作用来调节它们的靶mRNAs。正在进行的细菌碱基配对sRNA的特征已经开始揭示这些sRNA是如何参与全球调控网络的。这些网络可以分解成更小的调节电路,它们具有特有的行为和功能。在这篇综述中,我们描述了整合碱基配对sRNA的特定调控电路,以及每个电路在全球调控中的重要性。由于这些电路中的大多数最初被确定为转录网络中的网络基序,我们还讨论了为什么sRNAs可能比蛋白质转录因子更有助于转导环境信号。
Bacteria employ a range of RNA regulators collectively termed small RNAs (sRNAs) to help respond to changes in the environment. Many sRNAs regulate their target mRNAs through limited base pairing interactions. Ongoing characterization of base pairing sRNAs in bacteria has started to reveal how these sRNAs participate in global regulatory networks. These networks can be broken down into smaller regulatory circuits that have characteristic behaviors and functions. In this review, we describe the specific regulatory circuits that incorporate base pairing sRNAs and the importance of each circuit in global regulation. Since most of these circuits were originally identified as network motifs in transcriptional networks, we also discuss why sRNAs may be employed over protein transcription factors to help transduce environmental signals.
