Targeted Interventions in Biosynthesis Using Toehold Switches

Biosynthesis is a multi-step process in which simple substances are transformed into more complex substances by enzymes in the body. During biosynthesis, simple compounds undergo chemical reactions, transform into other compounds, or polymerize to form macromolecules. This process is usually accomplished in metabolic pathways. Intracellular biosynthesis includes the synthesis of proteins, lipids, nucleotides, and other substances. With the advent of gene-editing technology, humans want cells to synthesize specified substances, and therefore, the rise of synthetic biology. The goal of synthetic biology is to build artificial biological systems, linking "genes" into networks that allow cells to perform various tasks envisioned by designers. 

Conventional Synthetic Biology Tools

In the process of modifying or creating microorganisms, it is necessary to simplify, insert or reconstruct the genome of the chassis organism, and some synthetic biology tools are usually used. Efficient and precise gene-editing technology has become an effective means to solve these problems. For targeted intervention in cell biosynthesis, such as Red homologous recombination technology, zinc finger ribozyme technology, RNA interference technology, transcription activator effector protein nuclease technology, and the popular CRISPR technology. These methods efficiently edit genes so that cells can synthesize specific substances.

Toehold Switches in Biosynthesis

With the emergence of toehold switches, synthetic biology has another promising tool. Such de novo RNA elements can be used to construct RNA-based synthetic gene circuits to manipulate cellular biosynthesis, especially protein synthesis, by targeted manipulation of gene expression. At CD BioSciences, we have built a technology platform for toehold switches that can provide you with technical support for targeted intervention in transcriptional and translational regulation to make cells work for your purpose.
