Template:ETH Sim Input Rate
From 2006.igem.org
The input rates (PoPS) have been chosen in the range of mRNA transcription rate, which was estimated according to the following assumptions:
- E.coli cytoplasm volume is approximately 6.7*10-16 l
- average number of mRNA molecules: 10
- → concentrationmRNA = 10/(6.7*10-16 * 6.022*1023) M = 0.0248 μM
- at equilibrum, mRNA rate and degredation balance each other. Assuming half life period of 30min for mRNA, the result is
→ratemRNA = concentrationmRNA * log(2)/30 μM/min = 5.7265e-04 μM/min
Amplifying/damping the input rates by small constant factors has influence on the qualitative outcome of the simulation.
- it is thus important to know how strong the input of the gate has to be.
- we can regulate this by choosing/designing the predecessor gate accordingly or
- by changing the ribosome binding sites to strengthen/weaken the input signal.
We accounted for this by adding restriction enzyme sites to the DNA.
