Quercetin-3-sulfate 3'-sulfotransferase

Quercetin-3-sulfate 3'-sulfotransferase 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 Quercetin-3-sulfate 3'-sulfotransferase rather than just read about it. In short: Quercetin-3-sulfate 3'-sulfotransferase (EC 2.8.2.26) is an enzyme that catalyzes the chemical reaction It uses the cofactor 3'-phosphoadenosine-5'-phosphosulfate (PAPS) to transfer a sulfate group and gives adenosine 3',5'-bisphosphate as a byproduct. The enzyme characterised from Flaveria chlorifolia converts quercetin 3-O-sulfate to quercetin 3,3'-bissulfate.

Reference excerpt

Quercetin-3-sulfate 3'-sulfotransferase (EC 2.8.2.26) is an enzyme that catalyzes the chemical reaction

It uses the cofactor 3'-phosphoadenosine-5'-phosphosulfate (PAPS) to transfer a sulfate group and gives adenosine 3',5'-bisphosphate as a byproduct. The enzyme characterised from Flaveria chlorifolia converts quercetin 3-O-sulfate to quercetin 3,3'-bissulfate. The starting material is produced from quercetin by a similar reaction catalysed by the enzyme flavonol 3-sulfotransferase. This enzyme is transferase, specifically a sulfotransferases, which transfer sulfur-containing groups. The systematic name of this enzyme class is 3'-phosphoadenylyl-sulfate:quercetin-3-sulfate 3'-sulfotransferase. Other names in common use include flavonol 3'-sulfotransferase, 3'-Sulfotransferase, and PAPS:flavonol 3-sulfate 3'-sulfotransferase.

Worked examples

Example 1 — a first encounter with Quercetin-3-sulfate 3'-sulfotransferase

Start with the simplest possible case. Write down what Quercetin-3-sulfate 3'-sulfotransferase 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 Quercetin-3-sulfate 3'-sulfotransferase 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 Quercetin-3-sulfate 3'-sulfotransferase 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 Quercetin-3-sulfate 3'-sulfotransferase

In research: Quercetin-3-sulfate 3'-sulfotransferase 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 Quercetin-3-sulfate 3'-sulfotransferase 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: Quercetin-3-sulfate 3'-sulfotransferase is common in secondary-school and first-year university syllabi. It links to neighbouring topics EC 2.8.2, Enzymes of unknown structure, Quercetin, so understanding it makes those chapters shorter.
In everyday life: Look for Quercetin-3-sulfate 3'-sulfotransferase 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.
