Histidine N-acetyltransferase

Histidine N-acetyltransferase 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 Histidine N-acetyltransferase rather than just read about it. In short: Histidine N-acetyltransferase (EC 2.3.1.33) is an enzyme that catalyzes the chemical reaction The two substrates of this enzyme characterised from killifish are histidine and acetyl-CoA. Its products are N-acetyl-histidine and coenzyme A.

Key takeaways

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

Reference excerpt

Histidine N-acetyltransferase (EC 2.3.1.33) is an enzyme that catalyzes the chemical reaction

The two substrates of this enzyme characterised from killifish are histidine and acetyl-CoA. Its products are N-acetyl-histidine and coenzyme A. This enzyme belongs to the family of transferases, specifically those acyltransferases transferring groups other than aminoacyl groups. The systematic name of this enzyme class is acetyl-CoA:L-histidine N-acetyltransferase. Other names in common use include acetylhistidine synthetase, and histidine acetyltransferase.

Worked examples

Example 1 — a first encounter with Histidine N-acetyltransferase

Start with the simplest possible case. Write down what Histidine N-acetyltransferase 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 Histidine N-acetyltransferase 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 Histidine N-acetyltransferase 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 Histidine N-acetyltransferase

In research: Histidine N-acetyltransferase 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 Histidine N-acetyltransferase 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: Histidine N-acetyltransferase is common in secondary-school and first-year university syllabi. It links to neighbouring topics EC 2.3.1, EC 2.3 stubs, Enzymes of unknown structure, so understanding it makes those chapters shorter.
In everyday life: Look for Histidine N-acetyltransferase 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.
