Glutamine—phenylpyruvate transaminase

Glutamine—phenylpyruvate transaminase 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 Glutamine—phenylpyruvate transaminase rather than just read about it. In short: Glutamine-phenylpyruvate transaminase (EC 2.6.1.64) is a pyridoxal phosphate-dependent enzyme that catalyzes the chemical reaction The two substrates of this enzyme characterised from rat kidney are L-glutamine and phenylpyruvic acid. Its products are 2-oxoglutaramic acid and L-phenylalanine.

Key takeaways

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

Reference excerpt

Glutamine-phenylpyruvate transaminase (EC 2.6.1.64) is a pyridoxal phosphate-dependent enzyme that catalyzes the chemical reaction

The two substrates of this enzyme characterised from rat kidney are L-glutamine and phenylpyruvic acid. Its products are 2-oxoglutaramic acid and L-phenylalanine. This enzyme is a transferase, specifically a transaminase, that transfer nitrogenous groups. The systematic name of this enzyme class is L-glutamine:phenylpyruvate aminotransferase. Other names in common use include glutamine transaminase K, and glutamine-phenylpyruvate aminotransferase.

Structural studies As of late 2007, two structures have been solved for this class of enzymes, with PDB accession codes PDB: 1YIY and PDB: 1YIZ.

Worked examples

Example 1 — a first encounter with Glutamine—phenylpyruvate transaminase

Start with the simplest possible case. Write down what Glutamine—phenylpyruvate transaminase 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 Glutamine—phenylpyruvate transaminase 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 Glutamine—phenylpyruvate transaminase 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 Glutamine—phenylpyruvate transaminase

In research: Glutamine—phenylpyruvate transaminase 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 Glutamine—phenylpyruvate transaminase 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: Glutamine—phenylpyruvate transaminase is common in secondary-school and first-year university syllabi. It links to neighbouring topics EC 2.6.1, EC 2.6 stubs, Enzymes of known structure, so understanding it makes those chapters shorter.
In everyday life: Look for Glutamine—phenylpyruvate transaminase 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.
