Reference excerpt

Quercetin 2,3-dioxygenase (EC 1.13.11.24) is an enzyme that catalyzes the chemical reaction

The two substrates of this enzyme are quercetin and oxygen. Its products are 2-(3,4-dihydroxybenzoyloxy)-4,6-dihydroxybenzoic acid and carbon monoxide. This enzyme belongs to the family of oxidoreductases, specifically those acting on single donors with O2 as oxidant and incorporation of two atoms of oxygen into the substrate (oxygenases). The oxygen incorporated need not be derived from O2. The systematic name of this enzyme class is quercetin:oxygen 2,3-oxidoreductase (decyclizing). Other names in common use include quercetinase and flavonol 2,4-oxygenase. It has two cofactors: iron and copper.

Structural studies As of late 2007, six crystal structures have been solved for this class of enzymes, with PDB accession codes PDB: 1GQG, PDB: 1GQH, PDB: 1H1I, PDB: 1H1M, PDB: 1JUH, and PDB: 2H0V.

Worked examples

Example 1 — a first encounter with Quercetin 2,3-dioxygenase

Start with the simplest possible case. Write down what Quercetin 2,3-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 Quercetin 2,3-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 Quercetin 2,3-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 Quercetin 2,3-dioxygenase

In research: Quercetin 2,3-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 Quercetin 2,3-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: Quercetin 2,3-dioxygenase is common in secondary-school and first-year university syllabi. It links to neighbouring topics Copper enzymes, EC 1.13.11, Enzymes of known structure, so understanding it makes those chapters shorter.
In everyday life: Look for Quercetin 2,3-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.
