Web24 de jan. de 2024 · A high affinity interaction is commonly determined by a low dissociation rate (<10 -5 s -1) and a relative low equilibrium dissociation constant (<10 -9 M). Although a sufficient fast association rate enhances the forming of the complex, the dissociation rate determines the time that the two molecules stay together in complex. Web9 de mai. de 2024 · Pharmacology has characterized at least two distinct states of GPCRs, an active state with high affinity for agonists when coupled to G proteins and an inactive state with low affinity for agonists in the absence of G proteins ( 1 ), although a plethora of substates can also exist between these two extremes ( 3 – 7 ).
