Figure 1From: Diffusive coupling can discriminate between similar reaction mechanisms in an allosteric enzyme systemReaction mechanisms describing the allosteric activation of the phosphofructokinase by its product ADP. Hill-like activation as in the Sel'kov model [12] (A) and sequential activation as in the Monod-Wyman-Changeux mechanism [37] used in the Goldbeter model [13] (B) - shown for two ADP-binding subunits (n = 2).Back to article page
