L-lactate dehydrogenases catalyzes the conversion of L-lactate to pyruvatethe last step in anaerobic glycolysis. In contrast, D-malate, hydroxymalonate, and the keto form of oxaloacetate have been found to bind exclusively to the protonated form of the enzyme.

The loop undergoes a conformational change to shield the substrate and catalytic amino acids from deshidrovenasa solvent in response to the binding of the malate dehydrogenase: Glutamate has also been shown to inhibit malate dehydrogenase activity.

Pyruvate carboxylase Aspartate transaminase. Additionally, the formation of this complex enables glutatmate to react with aminotransferase without interfering activity of malate dehydrogenase. It is a large protein molecule with subunits weighing between 30 and 35 kDa.

NADH complex forms much more rapidly at higher pH values. Cholesterol side-chain cleavage enzyme Steroid beta-hydroxylase Aldosterone synthase Frataxin.

The Kcat value is In most organisms, malate dehydrogenase MDH exists as a homodimeric molecule and is closely related to lactate dehydrogenase LDH in structure. Malate dehydrogenase has also been shown to have a mobile loop region that plays a crucial role in the enzyme’s catalytic activity. Experiments have shown that Citrate can both allosterically activate and inhibit the enzymatic activity of malate dehydrogenase.

Studies have also indicated that this loop region is highly conserved in malate dehydrogenase. Studies have indicated that the binding of the enol form oxaloacetate with the malate dehydrogenase: Furthermore, it has been shown that alpha ketogluturate dehydrogenase can interact with mitochondrial aspartate aminotransferase to form a complex, which can then bind to malate dehydrogenase, forming a ternary complex that reverses inhibitory action on malate dehydrogenase enzymatic activity by glutamate.

The subunits are held together through extensive hydrogen-bonding and hydrophobic interactions. Citric acid cycle enzymes. Malate dehydrogenase quinone Quinoprotein glucose dehydrogenase. This oxidation step results in the elimination of a proton malati a hydride ion from the substrate.

Malate dehydrogenase EC 1. Several isozymes of malate dehydrogenase exist. Journal of Molecular Biology. Desyidrogenasa and Biophysical Research Communications. Kinetically, the binding of malate dehydrogenase to the binary complex of alpha ketogluturate dehydrogenase and aminotrannferase has been shown to increase reaction rate of malate dehydrogenase because the Km of malate dehydrogenase is decreased when it is bound as part of this complex.

Vitamin K epoxide reductase Vitamin-K-epoxide reductase warfarin-insensitive. This electrostatic stabilization helps facilitate the transfer of the proton.

This may be due to deviations observed in the kinetic behavior of malate dehydrogenase at high oxaloacetate and L-malate concentrations.

Malate dehydrogenase – Wikipedia

Although malate dehydrogenase is typically considered a reversible enzyme, it is believed that there is an allosteric regulatory site on the enzyme where citrate can bind to and drive the reaction equilibrium in either direction.

Additionally, the Arginine residues on the enzyme provide additional substrate specificity and binding through hydrogen bonding between the guanidinium side chain of the Arginine amino acid residues and the carboxylates of the substrate.

Glucose oxidase L-gulonolactone oxidase Xanthine oxidase.
