Glycoprotein N-palmitoyltransferase

Glycoprotein N-palmitoyltransferase is a biology 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 Glycoprotein N-palmitoyltransferase rather than just read about it. In short: In enzymology, a glycoprotein N-palmitoyltransferase (EC 2.3.1.96) is an enzyme that catalyzes the chemical reaction palmitoyl-CoA + glycoprotein ⇌ {\displaystyle \rightleftharpoons } CoA + N-palmitoylglycoprotein Thus, the two substrates of this enzyme are palmitoyl-CoA and glycoprotein, whereas its two products are CoA and N-palmitoylglycoprotein. This enzyme belongs to the family of transferases, specifically tho…

Key takeaways

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

Reference excerpt

In enzymology, a glycoprotein N-palmitoyltransferase (EC 2.3.1.96) is an enzyme that catalyzes the chemical reaction

palmitoyl-CoA + glycoprotein ⇌ {\displaystyle \rightleftharpoons } CoA + N-palmitoylglycoprotein Thus, the two substrates of this enzyme are palmitoyl-CoA and glycoprotein, whereas its two products are CoA and N-palmitoylglycoprotein. 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 palmitoyl-CoA:glycoprotein N-palmitoyltransferase. This enzyme is also called mucus glycoprotein fatty acyltransferase. This enzyme participates in aminosugars metabolism. This enzyme has at least one effector, Dithiothreitol.

Worked examples

Example 1 — a first encounter with Glycoprotein N-palmitoyltransferase

Start with the simplest possible case. Write down what Glycoprotein N-palmitoyltransferase claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In biology, 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 Glycoprotein N-palmitoyltransferase 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 Glycoprotein N-palmitoyltransferase 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 Glycoprotein N-palmitoyltransferase

In research: Glycoprotein N-palmitoyltransferase appears in biology 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 Glycoprotein N-palmitoyltransferase 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: Glycoprotein N-palmitoyltransferase 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 Glycoprotein N-palmitoyltransferase 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.
