The positive feedback loop of activation slightly modifies the oscillations. Oscillations are possible when the difference between Hilll's coefficients of the repression and activation is sufficiently high. The highly cooperative activation loop with a fast turnover slows down or even makes the ...
When Vinchanges, negative feedback changes the input to the amplifier in order to counteract the effect of the change in Vin. Conversely, positive feedback increases the effects of the change in Vin. The output (Vout) is equal to the sum of the Vinand feedback signals multiplied...
The relationship between the signal and the response to the signal is direct, meaning that both the signal and the response increase. The presence of Molecule B increases the production of Molecule B in this example of a positive feedback loop. Examples of Positive Feedback Positive feedback ...

σR regulon includes genes for itself and multiple thiol-reducing systems, which constitute positive and negative feedback loops respectively. We found that the positive amplification loop involves an isoform of σR (σR′) with an N-terminal extension of 55 amino acids, produced from an ...

One gene is enough and the positive transcriptional feedback signal does not need to activate a second repressor gene. This means that at the genetic level an explicit negative feedback loop is not necessary. The model needs neither cooperative binding reactions nor the formation of protein ...
