With such as dramatic difference in fluorescence lifetimes, we have been able to determine ALDH2 enzyme activity, the steady state NADH-ALDH2 complex concentration, the rate of rate of NADH displacement from NADH-ALDH2 complex and the dissociation constant for NADH with ALDH2 under a wide range of magnesium ion concentrations.

The four levels of the enzyme saturation with substrate S (S stands for PEP in this particular case) can be presented by the following schemes, where the substrate interaction with the first subunit is quantified by the dissociation constant K, affinity for the second substrate molecule is quantified by [alpha]K, and affinity for the third and fourth substrate molecules by [beta]K and [gamma]K, respectively [14].
