Taurine dioxygenase

Taurine dioxygenase 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 Taurine dioxygenase rather than just read about it. In short: Taurine dioxygenase (EC 1.14.11.17) is an enzyme that catalyzes the chemical reaction. It oxidises taurine using molecular oxygen, converting it to sulfite and aminoacetaldehyde.

Key takeaways

Taurine dioxygenase belongs to engineering; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Taurine dioxygenase to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Taurine dioxygenase from memory before moving on to harder problems.

Reference excerpt

Taurine dioxygenase (EC 1.14.11.17) is an enzyme that catalyzes the chemical reaction.

It oxidises taurine using molecular oxygen, converting it to sulfite and aminoacetaldehyde. This enzyme is an alpha-ketoglutarate-dependent hydroxylase with systematic name taurine, 2-oxoglutarate:O2 oxidoreductase (sulfite-forming). Other names in common use include 2-aminoethanesulfonate dioxygenase, and alpha-ketoglutarate-dependent taurine dioxygenase. It participates in taurine and hypotaurine metabolism.

Structural studies As of late 2007, 4 structures have been solved for this class of enzymes, with PDB accession codes PDB: 1GQW, PDB: 1GY9, PDB: 1OS7, and PDB: 1OTJ.

Mechanism The enzyme is a non-heme iron protein with ferryl active site where Fe(IV)=O is the species that transfers its oxygen to the substrate. The mechanism requires 2-oxoglutaric acid to activate the iron oxygen complex, and this gives succinic acid and carbon dioxide when the second atom of the molecular oxygen is removed. Ascorbic acid is also required to increase the turnover number of the enzyme by reducing any iron converted to Fe(III) back to the required Fe(II).

Worked examples

Example 1 — a first encounter with Taurine dioxygenase

Start with the simplest possible case. Write down what Taurine dioxygenase 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 Taurine dioxygenase 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 Taurine dioxygenase 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 Taurine dioxygenase

In research: Taurine dioxygenase 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 Taurine dioxygenase 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: Taurine dioxygenase is common in secondary-school and first-year university syllabi. It links to neighbouring topics Ascorbate enzymes, EC 1.14.11, EC 1.14 stubs, so understanding it makes those chapters shorter.
In everyday life: Look for Taurine dioxygenase 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.
