isozyme NAD-ME2 and chimeric mutant NAD-ME1q follow a sequential ordered Bi-Ter mechanism, NAD+ being the leading substrate followed by (S)-malate. Hetereodimer NAD-MEH can bind both substrates randomly. Interaction between NAD-ME1 and -ME2 generates a heteromeric isozyme NAD-MEH with a particular kinetic behaviour

isozyme NAD-ME2 and chimeric mutant NAD-ME1q follow a sequential ordered Bi-Ter mechanism, NAD+ being the leading substrate followed by (S)-malate. Isozyme NAD-ME1 and hetereodimer NAD-MEH can bind both substrates randomly. However, NAD-ME1 shows a preferred route that involves the addition of NAD+ first. interaction between NAD-ME1 and -ME2 generates a heteromeric isozyme NAD-MEH with a particular kinetic behaviour

-
NAD-ME1 has a regulatory site for L-malate that can also bind fumarate. L-Malate binding to this site elicits a sigmoidal and low substrate-affinity response, whereas fumarate binding turns NAD-ME1 into a hyperbolic and high substrate affinity enzyme. This effect is also observed when the allosteric site is either removed or altered. Fumarate is not really an activator, but suppresses the inhibitory effect of L-malate. Residues Arg50, Arg80 and Arg84 show different roles in organic acid binding. These residues form a triad, which is the basis of the homo and heterotrophic effects that characterize NAD-ME1

Arabidopsis NAD-ME1 is strongly stimulated by fumarate. Fumarate binding turns NAD-ME1 into a hyperbolic and high substrate affinity enzyme. This effect is also observed when the allosteric site is either removed or altered. Hence, fumarate is not really an activator, but suppresses the inhibitory effect of L-malate. Binding of L-malate and fumarate at the same allosteric site
