PlsrA-gfp-PlsrR-lsrR


Fluorescence intensity is decreased by LsrR repression.
This work is done by Hiroki Yoshise.

As we described in BBa_K649101, in this part, lsrK has mutation and does not work properly and oher genes work correctly.

We confirmed that LsrR represses lsrA promoter. We measured LsrR repression activity by using a plasmid (BBa_K649105) which have a lsrR gene downstream of lsrA promoter-gfp.By the LsrR repression, the fluorescence intensity decreased 3-fold. This result shows that LsrR successfully repressed lsrA promoter. The working part we created allow the use of AI-2 as a signaling molecule, which is a very powerful tool to build complex Synthetic Biology systems.
