Repressors
So far, we've been talking about repressors.
- Can't replace a computer with it, as it isn't quite fast enough.
- Defined NOT, AND, FOR, etc., devices
- Can use sender/receiver devices, not just boolean logic
- Start to think about sensors/actuators, etc.
Characteristics
What do we want to know about the physics/biology of our inverters?
- Toxicity
- Speed
- Signal levels
- Transfer function
- Load placed on cell
Do we care about the relation between the input and the output?
- We care about the range of the input signal
- How the output changes (transfer function)
How are we going to come up with answers?
Let's look at an inverter. Say the repressor controls something called [math]\displaystyle{ \lambda }[/math] cI.
- Model depends on physics of system
- Also going to encounter the science/biology of system
- [math]\displaystyle{ \lambda }[/math] is a phage that does such & such...
- [math]\displaystyle{ \lambda }[/math] repressor doesn't turn off in all instances, blah blah
Connection to BE.320
- [math]\displaystyle{ A + B = AB \ }[/math]
- [math]\displaystyle{ \frac{d(AB)}{dt} = k_{on}^{AB}-k_{off}^{AB} }[/math]
How quickly will our sample device work?
- Whereas the input signal is a discrete square wave, the output wave lags behind (latency) with a slightly rounded curve. [math]\displaystyle{ \DeltaT }[/math] is the latency between the time between otherwise max & min.
