Abstract

CRISPRi-based tools may enhance the design of synthetic gene circuits in bacteria.

Synthetic gene circuits are essential for programming cellular behavior.
Designing these circuits can be complex due to various influencing parameters.
Transcription factors have been the primary tools for circuit construction for two decades.
CRISPRi tools can provide significant advantages for larger circuits.
Unique design considerations are necessary when using CRISPRi for circuit development.

Simplified

Synthetic gene circuits are key elements of engineered biological systems that allow us to control and program cellular behavior. Yet, circuit design can be challenging to newcomers due to the numerous design choices and the abundance and variety of parameters that can influence circuit performance. While transcription factors have dominated the circuit construction toolbox for two decades, CRISPRi-based tools offer important benefits-especially for large circuits-but also require unique design considerations. Here I provide a detailed guide for designing CRISPRi circuits in bacteria, using the CRISPRlator, the first CRISPRi oscillator, as an example that illustrates the design process.
