Guide RNA (gRNA) target for XylE (middle of gene)

This part is a guide RNA (gRNA) that targets the middle of the XylE gene, when bound to Cas9.

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 XylE is not used in the conjugation project since we did not use any of the pigments in this project.

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

Conjugation Project

The XylE (middle) gRNA was not used in the Conjugation Project

Synthetic Circuit

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