Reaction List for pathway Lac_gene (Pathway Number 296)

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 reactions is not considered.

Degraded_lac
  This reaction denotes the degradation of Lac the half life of which is ten minutes. t1/2 = 0.693/k where k denotes kf Note: Rates had to scaled by approx 1.4 to get desired levels Elowitz, M. et al. (2000) Nature 403:335-338
