Model assumptions and relevance
- LuxR is at steady state
- A good approximation if LuxR gene is left in an active state while cells are growing in medium
- LuxR and AHL bind in a linear second order fashion
- This is not strictly true as LuxR and AHL bind using pseudo-Michaelis-Menten kinetics
- Gives a good approximation if LuxR is in excess of AHL (ie not saturated by AHL)
- Unlikely to occur all the time as LuxI levels increase to very high amounts
- LuxI can be ignored
- LuxI levels vary throughout, and it is these levels that are directly responsible for AHL production
- This could be a major flaw in the model
