Applications
The bistable is a very interesting tool. Its structure allows using any combination of either markers or functional genes which can have many applications in basic and applied sicence.
Here we show some ideas for possible uses for our basic and improved flip-flop system:
Application 1 – Big scale production of killer proteins
An applied use of the flip-flop could be the production of proteins that are highly toxic or even lethal for those bacteria that produce them (called “killer proteins”). Using the bistable we could get bacteria that synthesize those proteins only after a certain signal given in an optimal physiologycal moment or growth state that we want. This way we could be able to have bacteria that grow until reaching a certain density, and then inducing the change in the flip-flop state making our bacteria to synthesize fast an efficiently our favorite toxic protein. This has obvious advantages for antibody production, purification of useful molecules in clinic or any other industry etc.
Application 2 – Basic Research
A very extended way to regulate protein function among all life beings is postranslational modifications that set a protein or a complex in two different states. One of the best known of these modifications is phosphorilation. A protein can have several sites where can be phosphorilated and depending on where the phosphates are, the protein can be active, inactive, or can do different tasks. To study this phenomenon, scientist use either phosphomimetics, which are aminoacids (specifically glutamic acid and aspartic acid) that imitate the shape of a canonical phosphorilation but do not function as such or non-phophorilatable residues. That way it is possible to study the two states but only in separate cells. Thus, cloning the two mutant versions of a desired phohoprotein (constitutive phosphorylation and non-phosphorilatable) it would allow to study how this protein works with any phosphorilation pattern and to have a reversible system inside the same cell.
