Reference excerpt

The enzyme threo-3-hydroxyaspartate ammonia-lyase (EC 4.3.1.16) is an enzyme that catalyzes the chemical reaction

threo-3-hydroxy-L-aspartate ⇌ {\displaystyle \rightleftharpoons } oxaloacetate + NH3

Nomenclature This enzyme belongs to the family of lyases, specifically ammonia lyases, which cleave carbon-nitrogen bonds. The systematic name of this enzyme class is threo-3-hydroxy-L-aspartate ammonia-lyase (oxaloacetate-forming). Other names in common use include threo-3-hydroxyaspartate dehydratase, L-threo-3-hydroxyaspartate dehydratase, and threo-3-hydroxy-L-aspartate ammonia-lyase.

Worked examples

Example 1 — a first encounter with Threo-3-hydroxyaspartate ammonia-lyase

Start with the simplest possible case. Write down what Threo-3-hydroxyaspartate ammonia-lyase 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 Threo-3-hydroxyaspartate ammonia-lyase 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 Threo-3-hydroxyaspartate ammonia-lyase 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 Threo-3-hydroxyaspartate ammonia-lyase

In research: Threo-3-hydroxyaspartate ammonia-lyase 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 Threo-3-hydroxyaspartate ammonia-lyase 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: Threo-3-hydroxyaspartate ammonia-lyase is common in secondary-school and first-year university syllabi. It links to neighbouring topics EC 4.3.1, Enzyme stubs, Enzymes of unknown structure, so understanding it makes those chapters shorter.
In everyday life: Look for Threo-3-hydroxyaspartate ammonia-lyase 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.
