Specificity constant

• abstract: The specificity constant (k_{cat}/K_{M}), sometimes referred to as the kinetic efficiency, is a measure of the efficiency of an enzyme because the rate of the reaction directly varies with how frequently enzyme and substrate meet and how efficiently they bind in a solution. The specificity constant is a very useful kinetic value as it identifies the best substrate for a particular enzyme, in other words the specificity of an enzyme for a substrate.
