WebApr 10, 2024 · Background: A high-ranking scientist has recently proposed the need for direct estimation of the specificity constant rather than by calculation after a separate determination of maximum velocity and the Michaelis-Menten constant (KM). Objectives: The objectives of this study are to derive novel equations for the zero-arbitrary … WebThe kcat / Km value, or specificity constant, of the various substrates can be compared. That substrate with the highest value is the best substrate for the enzyme, accounting for the name specificity constant. The rate of any reaction is limited by the rate at which reactant molecules collide.
