Modeling Details of Repressilator


Key points of this modeling are:

  • LacI protein tends to form LacI dimer, which tends to form LacI tetramer further.
  • Only LacI tetramer binds with pLacI gene and thus repressing expression of its downstream genes.
  • TetR protein only forms dimer.
  • Only tetR dimer binds with pTet gene and thus repressing expression of its downstream genes.
  • One IPTG molecule binds with one LacI tetramer to form complex IPTG:LacI4.
  • cIlam protein only forms dimer.
  • Only cIlam dimer binds with pcIlam gene and thus repressing expression of its downstream genes.

Since there are 153 reactions in total, we only provide a screenshot (we strongly recommend users to run our example to learn more details about automatic modeling):
