Uracilylalanine synthase

Uracilylalanine synthase 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 Uracilylalanine synthase rather than just read about it. In short: Uracilylalanine synthase (EC 2.5.1.53) is an enzyme that catalyzes the chemical reaction The two substrates of this plant enzyme are O-acetylserine and uracil. Its products are acetic acid and willardine.

Key takeaways

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

Reference excerpt

Uracilylalanine synthase (EC 2.5.1.53) is an enzyme that catalyzes the chemical reaction

The two substrates of this plant enzyme are O-acetylserine and uracil. Its products are acetic acid and willardine. The enzyme has been characterised from pea. Although it transfers a 2-amino-2-carboxyethyl group from O-acetylserine, it has been shown not to be the same protein as cysteine synthase. This enzyme is a transferases, specifically those transferring aryl or alkyl groups other than methyl groups. The systematic name of this enzyme class is O3-acetyl-L-serine:uracil 1-(2-amino-2-carboxyethyl)transferase. Other names in common use include O3-acetyl-L-serine acetate-lyase (adding uracil), isowillardiine synthase, willardiine synthase, and 3-O-acetyl-L-serine:uracil 1-(2-amino-2-carboxyethyl)transferase.

Worked examples

Example 1 — a first encounter with Uracilylalanine synthase

Start with the simplest possible case. Write down what Uracilylalanine synthase 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 Uracilylalanine synthase 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 Uracilylalanine synthase 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 Uracilylalanine synthase

In research: Uracilylalanine synthase 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 Uracilylalanine synthase 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: Uracilylalanine synthase is common in secondary-school and first-year university syllabi. It links to neighbouring topics EC 2.5.1, Enzymes of unknown structure, Transferase stubs, so understanding it makes those chapters shorter.
In everyday life: Look for Uracilylalanine synthase 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.
