Innovation of our Project
By comparing the structural similarity of bacteriophage lambda and adenovirus, this project applies the synthetic biology strategy at the genomic level, transplanting the complex process of viral gene therapy vector production into prokaryotic cells. This approach makes the industrial production of gene therapy vector easier to standardize and manipulate, which coordinates the standardization, abstraction and decoupling principles of synthetic biology. As for the synthetic engineering of the targeted biobrick, we decouple the process of viral infection into two sub-steps, attachment and internalization, which are ensured by the synthetic targeted peptides and RGD domain respectively. Viewed from the overall project, this approach is equivalent to synthesizing a viable form (coinciding with Craig Venter’s approach on synthetic biology) that actually contributes to clinical uses. This reflects the synthetic biology’s extension in human practice by learning from nature.
