The approach to the Michaelis complex in lactate dehydrogenase: the substrate binding pathway.

Abstract excerpt

We examine here the dynamics of forming the Michaelis complex of the enzyme lactate dehydrogenase by characterizing the binding kinetics and thermodynamics of oxamate (a substrate mimic) to the binary lactate dehydrogenase/NADH complex over multiple timescales, from nanoseconds to tens of milliseconds. To access such a wide time range, we employ standard stopped-flow kinetic approaches (slower than 1 ms) and...
