Figure :Free phaR Protein content and the rate for them to bind to PHB granules. Because phaR is continuesly binding to the pHB granules, so there are less free phaR. At the same time, phaP is increasing much faster since less phaP is used to inhibit its transcription. But when there are too much phaP, the phaR will be replaced by phaP on the surface of the granules. What we see in this graph is that the amount of free phaR protein go down first and go up again. The cohesion rate is positive first but becomes negative later.
