For the high affinity sites the dissociation constant for interaction of toxin and receptor extrapolated to zero protein concentration is 9.2 X 10(-10) M. Competition with a variety of agonists and antagonists indicates that toxin binding exhibits the pattern expected for nicotinic acetylcholine receptors. Efficacy or potency, metabolic stability (half-life), and oral bioavailability are also improved in this step of the drug development process. As protein-protein interaction sites are known to be very flexible and binding pockets of small molecule modulators may not be (fully) accessible in all protein structures, PriaDock uses multiple protein conformations derived from crystal/NMR structures or molecular dynamics simulations to account for this flexibility. It therefore appears that both evolutionary selection pressures and physicochemical constraints shape the kinetic parameters of enzymes. computationally exhaustive techniques, such as Molecular Dynamics. stick representation and their corresponding positions of binding within the protein as atomic spheres.
