... order of magnitudebelow the sH of AfM1PDH.DiscussionKinetic mechanism of Af M1PDH and Af M2DHThe theory developed by Cook and Cleland is used todeduce the kinetic mechanism of AfM1PDH and AfM2DH ... binding of Man-ol1P and NAD+by AfM1PDH is not ordered, and that there isalso randomness in the binding of substrate and coen-zyme in each direction of the reaction catalyzed byAfM2DH. By way of ... also reported random binding of NAD+ and Man-ol1P [29]. It is reasonable toassume that random binding of reactants byAfM1PDH and AfM2DH occurs in rapid equilibrium, and the absence of curvature...
