Malate dehydrogenase (oxaloacetate-decarboxylating)

Malate dehydrogenase (oxaloacetate-decarboxylating) is a engineering topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Malate dehydrogenase (oxaloacetate-decarboxylating) rather than just read about it. In short: In enzymology, a malate dehydrogenase (oxaloacetate-decarboxylating) (EC 1.1.1.38) is an enzyme that catalyzes the chemical reaction The two substrates of this enzyme are (S)-malic acid and oxidised nicotinamide adenine dinucleotide (NAD+). Its products are pyruvic acid, carbon dioxide, and reduced NADH.

Reference excerpt

In enzymology, a malate dehydrogenase (oxaloacetate-decarboxylating) (EC 1.1.1.38) is an enzyme that catalyzes the chemical reaction

The two substrates of this enzyme are (S)-malic acid and oxidised nicotinamide adenine dinucleotide (NAD+). Its products are pyruvic acid, carbon dioxide, and reduced NADH. This enzyme belongs to the family of oxidoreductases, specifically those acting on the CH-OH group of donor with NAD+ or NADP+ as acceptor. The systematic name of this enzyme class is (S)-malate:NAD+ oxidoreductase (oxaloacetate-decarboxylating). Other names in common use include malic enzyme, pyruvic-malic carboxylase, NAD+-specific malic enzyme, NAD+-malic enzyme, and NAD+-linked malic enzyme. This enzyme participates in pyruvate metabolism.

Structural studies As of late 2007, 6 structures have been solved for this class of enzymes, with PDB accession codes PDB: 1DO8, PDB: 1EFK, PDB: 1EFL, PDB: 1GZ3, PDB: 1LLQ, PDB: 1O0S, PDB: 1PJ2, PDB: 1PJ3, PDB: 1PJ4, PDB: 1PJL, PDB: 1QR6, PDB: 1WW8, and PDB: 2DVM.

Worked examples

Example 1 — a first encounter with Malate dehydrogenase (oxaloacetate-decarboxylating)

Start with the simplest possible case. Write down what Malate dehydrogenase (oxaloacetate-decarboxylating) claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In engineering, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Malate dehydrogenase (oxaloacetate-decarboxylating) before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Malate dehydrogenase (oxaloacetate-decarboxylating) ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Malate dehydrogenase (oxaloacetate-decarboxylating)

In research: Malate dehydrogenase (oxaloacetate-decarboxylating) appears in engineering research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Malate dehydrogenase (oxaloacetate-decarboxylating) in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Malate dehydrogenase (oxaloacetate-decarboxylating) is common in secondary-school and first-year university syllabi. It links to neighbouring topics EC 1.1.1, Enzymes of known structure, NADH-dependent enzymes, so understanding it makes those chapters shorter.
In everyday life: Look for Malate dehydrogenase (oxaloacetate-decarboxylating) outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
