How to calculate km in michaelis menten
Web1 1. Introduction 2 The fundamental equation of enzyme kinetics is the Michaelis{Menten 3 (MM) equation, which relates the rate of an enzyme-catalyzed reaction to 4 the concentration of substrate [1, 2]. The MM equation is nowadays derived 5 using the steady-state assumption as proposed by Briggs and Haldane [3]. It 6 is characterized by two … WebThe assays were used in accordance with the manufacturer’s protocol to calculate (GraphPad Prism) the Michaelis-Menten parameters K m and V MAX. For the assay test compounds were serially diluted to produce an assay concentration range of 0–300 μM with the kinetics of ATP turnover examined over 30 min at 37°C.

WebUsing the above assumptions, we can derive the Michaelis-Menten equation (see figure 2): The term with rate constants in (figure 2, eq 7) is substituted by the Michaelis constant, Km (Michaelis, Menten, Briggs and Haldane introduced this constant!) giving (figure 2, eq 8). We assume a fast binding step and a slow catalytic step. WebDefinition.
