Knockdown of Bifunctional BirA enzyme

What it is?

By using the CRISPRi system, we are able to decrease the expression of the Bifunctional BirA enzyme which is an enzyme to consume the biotin in E. coli. In our project, we are aiming at biosynthesizing biotin through the metabolic pathways to generate more biotin in E. coli.

Usage and Biology

With the CRISPRi/dCas9 system targeting the bifunctional BirA enzyme after the production of biotin, the dCas9 system will attach to the enzyme, blocking other DNA from combining with the enzyme. Thus, the enzyme would be in a temporary dysfunctional state.
