Green Light Module

We have had marked success with our Green Light Module. Not only is the magenta pigment bright and evenly synthesised, but we have also managed to show magenta synthesis is inhibited by exposure to white light. We are currently working on showing that green light specifically switches off magenta production.

Red Light Module output Brick with BglII and BamHI restriction sites

The two ends of GFP have been ligated together to form a complete, working protein in the successful Gibson assembly of our output bricks. GFP is constitutively expressed within DH5α cells as endogenous ENVZ phosporylates endogenous OmpR as a component of osmolarity sensing. Endogenous OmpR then binds to OmpF. Thus our output brick is working as expected. In order to test whether the output brick can be implemented into the Red light pathway and ENVZ- strain should be used to avoid false positives.
