Project Description

The aim of this project is to create a cell that can go through a sequence of four distinct states in response to a timed pattern of light-on, light-off.

This project makes use of parts from EPF Lusanne '09 (the LOVTAP light activated promoter), PKU '07/'09 (bistable switch, AND gate), and Missouri Western State University '08 (Hybrid promoter). Our goal is to show that it is possible and easy to create entirely new cell logic systems from parts that already exist in the registry.

Project 2 - TAT-PTD

E.Cargo

We designed a modular Tat-Linker Biobrick that will allow for easy fusion of the Tat-PTD to any other biobricked proteins. Specifically, we aimed to fuse this Tat-Linker in RFC25 format to two bacterial transcription factors, LacI and AraC, with the intent of using the two Tat-TFs as a tool to induce transient gene expression in E. coli without the need to follow through with more time-consuming cell transformation protocols. To test these Tat-TFs, we designed corresponding reporter constructs. We saw a potential application in the portion of the Light-Pattern Controlled Circuit of our project, as well as in any other future genetic circuits that require part-by-part testing.
