WebOct 11, 2013 · This ability grants you an alternate version of Bind Affinity. Rank Requirements WebFor enzymes, Km can often serve as a surrogate for Kd, so low Km = high affinity = strong binding. The reason is that Kd is a dissociation constant. It measures the tendency of the protein-ligand complex to break apart. If it is unlikely to break apart, it has a low Kd, meaning it's likely to stay stuck together, so binding is strong. 6. level 2. crystal marie

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 ... WebNo, affinity reflects bonding. Km is measured using Vmax, but the absolute value of Vmax is totally irrelevant for Km. It merely reflects 0.5vmax, whatever the absolute value of Vmax. You are coupling Km and Vmax, while in reality Km says nothing about speed or product. It says something about substrate. Period. – AliceD ♦ Jan 25, 2015 at 14:47
