基于转录因子(TF)的生物传感器被广泛用于检测代谢物和调节响应于代谢物的细胞通路。几个挑战阻碍了基于TF的传感器直接应用于新的宿主或代谢途径,这通常需要广泛的调整以实现最佳性能。这些调整策略可以涉及转录或翻译控制,这取决于感兴趣的参数。在这篇综述中,我们强调了最近的策略工程TF为基础的生物传感器,以获得所需的性能,并讨论了其他的设计考虑,可能会影响生物传感器的性能。我们还研究了这些传感器的应用,并提出了进一步工作的重要领域,以继续推进小分子生物传感器。
Transcription factor (TF)-based biosensors are widely used for the detection of metabolites and the regulation of cellular pathways in response to metabolites. Several challenges hinder the direct application of TF-based sensors to new hosts or metabolic pathways, which often requires extensive tuning to achieve the optimal performance. These tuning strategies can involve transcriptional or translational control depending on the parameter of interest. In this review, we highlight recent strategies for engineering TF-based biosensors to obtain the desired performance and discuss additional design considerations that may influence a biosensor’s performance. We also examine applications of these sensors and suggest important areas for further work to continue the advancement of small-molecule biosensors.
