Maltose O-acetyltransferase

Maltose O-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 Maltose O-acetyltransferase rather than just read about it. In short: In enzymology, a maltose O-acetyltransferase (EC 2.3.1.79) is an enzyme that catalyzes the chemical reaction acetyl-CoA + maltose ⇌ {\displaystyle \rightleftharpoons } CoA + 6-O-acetyl-alpha-D-glucopyranosyl-(1->4)-D-glucose Thus, the two substrates of this enzyme are acetyl-CoA and maltose, whereas its two products are CoA and [[6-O-acetyl-alpha-D-glucopyranosyl-(1->4)-D-glucose]]. This enzyme belongs to the family…

Key takeaways

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

Reference excerpt

In enzymology, a maltose O-acetyltransferase (EC 2.3.1.79) is an enzyme that catalyzes the chemical reaction

acetyl-CoA + maltose ⇌ {\displaystyle \rightleftharpoons } CoA + 6-O-acetyl-alpha-D-glucopyranosyl-(1->4)-D-glucose Thus, the two substrates of this enzyme are acetyl-CoA and maltose, whereas its two products are CoA and [[6-O-acetyl-alpha-D-glucopyranosyl-(1->4)-D-glucose]]. 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:maltose O-acetyltransferase. Other names in common use include maltose transacetylase, maltose O-acetyltransferase, and MAT.

Structural studies As of late 2007, 3 structures have been solved for this class of enzymes, with PDB accession codes PDB: 1OCX, PDB: 2IC7, and PDB: 2P2O.

Worked examples

Example 1 — a first encounter with Maltose O-acetyltransferase

Start with the simplest possible case. Write down what Maltose O-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 Maltose O-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 Maltose O-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 Maltose O-acetyltransferase

In research: Maltose O-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 Maltose O-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: Maltose O-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 known structure, so understanding it makes those chapters shorter.
In everyday life: Look for Maltose O-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.
