Accession and Pathway Details

Accession Name	Accession No.	Accession Type	Pathway Link
Repressilator	68	Network	Lambda-cl_gene,  Lac_gene,  TetR_gene
This is a network model termed as Repressilator in which LacI inhibit transcription of tetR which in turn inhibit transcription of Lambda phage. This model simulates the result as per the Fig 1c of the paper : Elowitz MB, Leibler S., Nature. 2000 Jan 20;403(6767):335-8.

TetR_operator_1st_bound acting as a Substrate in a reaction in  Repressilator Network

Kd is calculated only for second order reactions, like nA+nB <->nC or nA<->nC+nD, where n is number and A,B,C,D are molecules, where as for first order reactions Keq is calculated. Kd for higher order reaction are not consider.
