Figure 3. Transient Gα^GTP production in mode 3.

In conditions when Gα^GTP transient is produced, its amplitude is largely under GPCR control, while its period is largely under the negative GAP control. Only [βγ] (broken line) and [Gα^GTP] (continuous line) are shown. Curve presentation, starting concentration of the components, and the Michaelis–Menten constants are as in Figure 2. Kinetic parameters, other than those shown, are: k_ass=0.0001 nM⁻¹·s⁻¹; k_diss=20 s⁻¹; k_hydr=5 s⁻¹.
