WebBoth the inhibitor and the substrate do not stick on the enzyme for ever. The higher its affinity is the longer it stays. The inhibitor can be replaced by a higher substrate concentration. You need more substrate to get the 0,5-Vmax --> Km (substarte) increases. WebApr 26, 2024 · Typically, binding affinity is represented by the equilibrium dissociation constant K D, the concentration of ligand at which half the binding sites on a biomolecule are occupied at equilibrium. The K D value describes the propensity of a complex (BL) to dissociate into its original components (B and L), in this case, the biomolecule and its ...
