Glycoprotein O-fatty-acyltransferase

Glycoprotein O-fatty-acyltransferase 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 O-fatty-acyltransferase rather than just read about it. In short: In enzymology, a glycoprotein O-fatty-acyltransferase (EC 2.3.1.142) is an enzyme that catalyzes the chemical reaction palmitoyl-CoA + mucus glycoprotein ⇌ {\displaystyle \rightleftharpoons } CoA + O-palmitoylglycoprotein Thus, the two substrates of this enzyme are palmitoyl-CoA and mucus glycoprotein, whereas its two products are CoA and O-palmitoylglycoprotein. This enzyme belongs to the family of transferases, sp…

Key takeaways

Glycoprotein O-fatty-acyltransferase 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 O-fatty-acyltransferase to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Glycoprotein O-fatty-acyltransferase from memory before moving on to harder problems.

Reference excerpt

In enzymology, a glycoprotein O-fatty-acyltransferase (EC 2.3.1.142) is an enzyme that catalyzes the chemical reaction

palmitoyl-CoA + mucus glycoprotein ⇌ {\displaystyle \rightleftharpoons } CoA + O-palmitoylglycoprotein Thus, the two substrates of this enzyme are palmitoyl-CoA and mucus glycoprotein, whereas its two products are CoA and O-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 fatty-acyl-CoA:mucus-glycoprotein fatty-acyltransferase. This enzyme is also called protein acyltransferase.

Worked examples

Example 1 — a first encounter with Glycoprotein O-fatty-acyltransferase

Start with the simplest possible case. Write down what Glycoprotein O-fatty-acyltransferase 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 O-fatty-acyltransferase 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 O-fatty-acyltransferase 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 O-fatty-acyltransferase

In research: Glycoprotein O-fatty-acyltransferase 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 O-fatty-acyltransferase 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 O-fatty-acyltransferase 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 O-fatty-acyltransferase 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.
