WebIn chemistry and biochemistry, a dissociation constant is a specific type of equilibrium constant that measures the propensity of a larger object to separate (dissociate) reversibly into smaller components, as when a complex falls apart into its component molecules, or when a salt splits up into its component ions. WebThe dissociation rate constant allows the calculation of the time during which a reversible proteinase/inhibitor complex remains undissociated in vivo in the presence of a dissociating agent ( e.g. a biological substrate).

WebThe dissociation constant, K(d) , is an important parameter for characterizing protein-protein interaction affinities. SUMOylation is one of the important protein post-translational modifications and it involves a multi-step enzymatic cascade reaction, resulting in peptide activation and substrate conjugation.
