Kinetic Network
Firstly we established a reaction network for the DNA binding process of Luminesensor. Previous works by other scientists indicate that the Vivid (VVD) protein, a sensing domain of Luminesensor, dimerizes in the presence of light,[1] and the LexA protein, a binding domain of Luminesensor, binds at specific sequences on DNA predominantly when coupled[2] and subsequently represses the interest gene. By combining with the mechanisms of the two functional domains of Luminesensor, we concluded with the following kinetic network:
Fig 1. Kinetic Network of our Luminesensor
where
- L : Luminesensor,
- LG : the ground state --- with its VVD N-cap locked,
- LA : the active state --- with its VVD N-cap released,
- DL : the specific DNA binding site to Luminesensor.
Since no multi-intermediate reactions are hidden in the network above, all reactions can be regarded as elementary reactions.
