Represilator

A brief review to compare

  • What?.

A loop negative system.

  • Parameters?.

Degradation of the mRNA, protein and the rate of transcription.

Perspectives for our system

  • Goes to a stable state.

Limitants -> lifespan of E. coli?, luciferin?.

"If is all on, we expect, that stuck there, but if one system turn off, maybe there is a stochastic component".

LOVTAP System

Lifespan TetR

  • We need a tag for increase the degradation of our repressor.

[math]\displaystyle{ δTetR= β - αTetRο }[/math]

We require a formula:

[math]\displaystyle{ F([TetR]) = Pops }[/math]

But what happen with the production of endougenos TetR?, exists?.

  • No... haha, it seems to be in a RESISTANCE plasmid.

Green emission

Input Pops -> Photons.

τ → ∞ -> [math]\displaystyle{ [14-CHO]=k }[/math]

  • This because the action of deg. and the production of CDE by M. acid tend to stabilize

Again we need to propose a formula:

[math]\displaystyle{ [LuxAB]=Pops }[/math]

Pathway

[math]\displaystyle{ LuxAB-FMNH }[/math]2[math]\displaystyle{ -O }[/math]2[math]\displaystyle{ -RCHO -\gt LuxAB + FMN + R-COOH + H }[/math]2[math]\displaystyle{ O + Light }[/math]

And the enzymes work in this form (Daniela has the references in German :S):

[math]\displaystyle{ Acid M. - }[/math]LuxD[math]\displaystyle{ \gt C }[/math]13[math]\displaystyle{ H }[/math]27[math]\displaystyle{ -COOH - }[/math]LuxE[math]\displaystyle{ \gt C }[/math]13[math]\displaystyle{ H }[/math]27[math]\displaystyle{ Co-Amp - }[/math]LuxC[math]\displaystyle{ \gt 14-COOH }[/math]

Here we see:

  • It appears that the product of the aldehyde can enter in the recicle pathway of LuxC and LuxE
  • We assume that C & E enzymes will be ocuppied with more substrate than the D, that only receives the membrane acid to form R-COOH. This mean, we need a major concentration of LuxCE than LuxD

Modelling with a Michael-Menten paradigm

Perspectives

It is relevant?:

  • Formation of the dimer A|B
  • Formation of the complex FMN-AB
  • Formation of the complex R-COOH-FMN-AB
  • Temperature

Can we assume Micahel-Menten equation?

To find list

  • Rate of deg. 14-CHO
  • Distribution of the acid trough the membrane
  • Size of the cell
  • Rates of transcription
  • Parameters that affects the emission.
