Full equations
1 Notations
1.1 Notation principles
Every relevant substance in the cell is denoted with uppercase letters which describes the substance, and a subscript which encodes the scale in which the amount of the substance is measured by the variable. For example, if we have a substance Y,
- its amount inside a single cell is denoted by Yin
- its amount inside all the cells together (its total amount inside the cells) is denoted by Ysum
- its amount outside all the cells (its external amount) is denoted by Yout
2 A list of all the notations we used
Substances:
- A - AHL (The auto inducer, a short for N-Acyl homoserine lactone).
- L - LuxR (a transciptional activator protein)
- LA - the complex LuxR and AHL form together.
- LA2 - the dimer we get when two LuxR-AHL complexes bind together.
- aa - Aiia (a AHL-lactonase).
- a1 - plasmids with an unactivated LuxR promotor.
- a2 - plasmids with an activated LuxR promotor.
- RNATetR - RNA strands of the TetR gene.
- TetR - Tet Repressor protein we use.
- b0 - plasmids with an unactivated Tet promotor.
- b1 - plasmids with an activated Tet promotor. ccbd - Toxin we use to kill the cell.
- X - any gene we want to measure the amount of it that will be produced by the bacteria colony. For example, it might represent the amount of a certain drug the bacteria produce.
Other quantitie of interest:
- N - number of bacteria. The bacteria are divided to two groups
- N+ - bacteria with our plasmid.
- N- - bacteria without our plasmid (in other words, bacteria that lost the plasmids we introduced into them).
- V - volume of the relevant scale. That means,
- Vout - the volume of the space outside the cells.
- Vsum - the volume of the total space inside all the cells.
- w - width of the cell membrane.
Constants
- C1 - C18 - different reaction constants.
- T+ - plamid positive generation time.
- T- - plamid free generation time.
- p - the chance to loose a plasmid.
- D- AHL diffusion constant.
3 Reactions
Initial conditions
- AHLout - how much AHL we put.
- a0 - initial number of strands (probably plasmid number).
- a1 - 0.
- b0 - initial number of strands (probably plasmid number). Sounds equal to a0(t=0) .
- b1 - 0.
- N+ - the number of cells we have at the beginning.
- N- - 0.
- all the rest - 0.
