In order to get the oxaloacetate out of the mitochondria, malate dehydrogenase reduces it to malate, and it then traverses the inner mitochondrial membrane.
Click on genes, proteins and metabolites below to link to respective articles. The malate dehydrogenase family contains L-lactate dehydrogenase and Lhydroxyisocaproate dehydrogenases.
Citrate synthase Aconitase Isocitrate dehydrogenase Oxoglutarate dehydrogenase complex Succinyl coenzyme A synthetase Fumarase Malate dehydrogenase. The loop undergoes a conformational change to shield the substrate and catalytic amino acids from the solvent in response to the binding of the malate dehydrogenase: Genes on human chromosome 2 Genes on human deshjdrogenasa 7 EC 1.
Vitamin K epoxide reductase Vitamin-K-epoxide reductase warfarin-insensitive. Studies deshidrogsnasa also indicated that this loop region is highly conserved in malate dehydrogenase. Randell; Wolfe, Allison B. In contrast, D-malate, hydroxymalonate, and the keto form of oxaloacetate have been found to bind exclusively to the protonated form of the enzyme.
This promotes the binding of malate dehydrogenase to these substrates. In most organisms, malate dehydrogenase MDH exists as a homodimeric molecule and is closely related to lactate dehydrogenase LDH in structure. Each subunit of the malate dehydrogenase dimer has two distinct domains that vary in structure and functionality.
Alternative oxidase Electron-transferring-flavoprotein dehydrogenase. L-lactate dehydrogenases catalyzes the conversion of L-lactate deshifrogenasa pyruvatethe last step in anaerobic glycolysis. This oxidation step results in the elimination of a proton and a hydride ion from the substrate.
Life at the Molecular Level 4th ed. Carnitine palmitoyltransferase I Long-chain-fatty-acid—CoA ligase.
Citric acid cycle enzymes. The subunits are held together through extensive hydrogen-bonding and hydrophobic interactions.
Studies have also identified a mobile loop in malate dehydrogenase that participates in the catalytic activity of the enzyme. Glucose oxidase L-gulonolactone oxidase Xanthine oxidase.
Structure of the protein with attached cofactors.
Malate dehydrogenase – Wikipedia
Retrieved from ” https: In its active state, MDH undergoes a conformational change that encloses the substrate to minimize solvent exposure and to position key residues in closer proximity to the substrate. As a result, at lower pH values malate dehydrogenase binds preferentially to D-malate, hydroxymalonate, and keto-oxaloacetate. For other uses, see Malate dehydrogenase disambiguation. Once in the cytosol, the malate is oxidized back to oxaloacetate by cytosolic malate dehydrogenase. General Physiology and Biophysics.
Trends in Biochemical Sciences. From Wikipedia, the free encyclopedia. Experiments have shown that Citrate can both allosterically activate and inhibit dedhidrogenasa enzymatic activity of malate dehydrogenase.
Pyruvate in the mitochondria is acted upon by pyruvate carboxylase to form oxaloacetate, a citric acid cycle intermediate.
