Design and Synthesis of Gene Circuits

One of the main goals of synthetic biology is to make biological systems rebuilding and re-tooling easier. Synthetic biology is commonly referred as biological engineering, with principles similar to how people assemble computers with various spare parts. Synthetic biologists hope to standardize core bioelements (such as enzymes, genetic circuits, metabolic pathways, etc.) and integrate these standardized ” bio-elements ” step by step to construct systems with specific functions and even synthesize new biological individuals.

The emergence of a new generation of gene synthesis technologies is represented by our next generation DNA synthesis platform. This platform is utilized in the construction of metabolic pathways or the synthesis of small genomes with high throughput and low-cost margins. With the development of sequencing and gene synthesis technologies, scientists areattempting to reprogram gene circuits and applications to change the direction of biological functions. Presently, synthetic biology has been widely applied in research fields including biology, medicine and new species synthesis.

  • In 2003, Jay Keasling and his research team were the first to reconstruct the biosynthetic pathway of artemisinic acid in E.coli. This accomplishment was the first functional verification of this metabolic pathway. Over the next 10 years, Jay Keasling and his team positively improved host selection and optimization, and industrialization.
  • Some important natural products, such as terpenoids, polyketides, non-ribosomal peptides, alkaloids etc. have been successfully synthesized through ectopic reconstruction of metabolic pathways.
  • In 2010, Craig Venter and his research team replaced mycoplasma cells in wild goats with genomic DNA from chemically synthesized Mycoplasma mycoides JCVI-syn1.0. In doing so, they successfully achieved self-duplication, which had the milestone significance in “artificial life”.
