Guide RNA (gRNA) target for GFP

This part is a guide RNA (gRNA) that targets the GFP gene, when bound to Cas9. It also contains a cleavage site recognized by the Csy4 enzyme which allows it to be cleaved from neighboring DNA/RNA.

Usage and Biology

In both of our projects, we used gRNAs and dCas9 as:

1) To specifically target and repress the "virulence gene" (we used flourescent proteins as a proof of concept) in our conjugation project. However, the gRNA for GFP is not used in the conjugation project since the green fluorescent protein was used to represent our donor strain of the project.

2) Improve past circuits with better decision making by using dCas9 instead of traditional repressors.

Conjugation Project

The GFP gRNA was not used in the Conjugation Project

Synthetic Circuit

In the Synthetic Circuit, the target is the GFP gene that would be located in the Low Concentration Pathway. The purpose of the gRNA is to prevent any possibility of the GFP gene expressing, due to a possible leaky promoter, when the High Concentration Pathway is being induced.
