- A light-sensitive promoter and/or a time sensitive promoter.
- We would also like to have a promoter that will turn genes "on" at specific times, such as every minute (or whatever designated time you want). In this way, you could enable cyclic cellular functions.
- The applications associated with this tool are expansive innature, and we would make great contributions to biobricks with these promoters.
What We Know
What We Don't Know (but need to know)
The Voigt Lab did this Voigt Lab:
- Engineering Two-Component Systems. Bacteria respond to their environment using membrane-bound sensors, which interact with intracellular response regulators to control gene expression. These systems are remarkably modular and new sensors can be built using in vitro recombination to swap protein domains. We demonstrated this process by fusing the light sensing domain from a cyanobacterium with a signal transduction domain from E. coli to create a strain that can respond to light. We are refining this strategy to create new sensors as well as studying the downstream signal processing events that occur once a sensor is activated.
- This process would probably take longer than 10 weeks, but is there a way we can shorten it to fit our goals?
- Chris - How is this different from synthetic oscillators? ie. The repressilator and the Hasty oscillations?
