WebKinetics of Calcium and Magnesium Binding. The dissociation constant is the ratio of the off rate to the on rate: K d (M) = k off (s −1)/k on (M −1 s −1). The rate limiting dehydration of Ca (H 2 O) 7 21 is fast, ~10 8.0 s −1; while that of Mg (H 2 O) 6 21 is slow, ~10 4.6 s −1. This difference reflects the loose pentagonal ... The binding constant, or affinity constant/association constant, is a special case of the equilibrium constant K, and is the inverse of the dissociation constant. It is associated with the binding and unbinding reaction of receptor (R) and ligand (L) molecules, which is formalized as: R + L ⇌ RL The reaction is characterized by the on-rate constant kon and the off-rate constant koff, which h…

WebReceptor–ligand binding kinetics also involves the on- and off-rates of binding. A main goal of receptor–ligand kinetics is to determine the concentrations of the various kinetic species (i.e., the states of the receptor and ligand) at all times, from a given set of initial concentrations and a given set of rate constants. WebMay 1, 2024 · The reason that calmodulin seems to favor calcium ions rather than magnesium ions is related to the binding constants of each ion. Calmodulin can exist while bound to other ions, such as magnesium, but if there is a higher concentration of calcium, the calcium ions will immediately compete out the magnesium ions to occupy calcium …
