Reference excerpt

In enzymology, glyceraldehyde-3-phosphate dehydrogenase (NAD(P)+) (EC 1.2.1.59) is an enzyme that catalyzes the chemical reaction

The three substrates of this enzyme are D-glyceraldehyde 3-phosphate, phosphate (Pi), and oxidised nicotinamide adenine dinucleotide (NAD+). Its products are 1,3-bisphosphoglyceric acid, reduced NADH, and a proton. The enzyme can use nicotinamide adenine dinucleotide phosphate as an alternative cofactor. This enzyme belongs to the family of oxidoreductases, specifically those acting on the aldehyde or oxo group of a donor with NAD+ or NADP+ as an acceptor. The systematic name of this enzyme class is D-glyceraldehyde 3-phosphate:NAD(P)+ oxidoreductase (phosphorylating). Other names in common use include triosephosphate dehydrogenase (NAD(P)) (phosphorylating), and glyceraldehyde-3-phosphate dehydrogenase (NAD(P)) (phosphorylating).

Structural studies As of late 2007, only one structure has been solved for this class of enzymes, with the PDB accession code PDB: 2CZC.

Worked examples

Example 1 — a first encounter with Glyceraldehyde-3-phosphate dehydrogenase (NAD(P)+)

Start with the simplest possible case. Write down what Glyceraldehyde-3-phosphate dehydrogenase (NAD(P)+) 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 Glyceraldehyde-3-phosphate dehydrogenase (NAD(P)+) 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 Glyceraldehyde-3-phosphate dehydrogenase (NAD(P)+) 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 Glyceraldehyde-3-phosphate dehydrogenase (NAD(P)+)

In research: Glyceraldehyde-3-phosphate dehydrogenase (NAD(P)+) 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 Glyceraldehyde-3-phosphate dehydrogenase (NAD(P)+) 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: Glyceraldehyde-3-phosphate dehydrogenase (NAD(P)+) is common in secondary-school and first-year university syllabi. It links to neighbouring topics EC 1.2.1, EC 1.2 stubs, Enzymes of known structure, so understanding it makes those chapters shorter.
In everyday life: Look for Glyceraldehyde-3-phosphate dehydrogenase (NAD(P)+) 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.
