Reference excerpt

Lignostilbene alphabeta-dioxygenase (EC 1.13.11.43) is an enzyme that catalyzes the chemical reaction

The two substrates of this enzyme are 3,3'-dimethoxy-trans-stilbene-4,4'-diol and oxygen. Its product is two equivalents of vanillin. The enzyme from Pseudomonas species cleaves the ethylene bond in a general class of natural lignin derivatives called lignostilbenes. 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 1,2-bis(4-hydroxy-3-methoxyphenyl)ethylene:oxygen oxidoreductase (alphabeta-bond-cleaving). It employs one cofactor, iron.

Worked examples

Example 1 — a first encounter with Lignostilbene alphabeta-dioxygenase

Start with the simplest possible case. Write down what Lignostilbene alphabeta-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 Lignostilbene alphabeta-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 Lignostilbene alphabeta-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 Lignostilbene alphabeta-dioxygenase

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