Luteolin-7-O-diglucuronide 4'-O-glucuronosyltransferase

Luteolin-7-O-diglucuronide 4'-O-glucuronosyltransferase 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 Luteolin-7-O-diglucuronide 4'-O-glucuronosyltransferase rather than just read about it. In short: Luteolin-7-O-diglucuronide 4'-O-glucuronosyltransferase (EC 2.4.1.191) is an enzyme that catalyzes a chemical reaction which converts a luteolin di-glucuronide, luteolin 7-O-(β-D-glucuronosyl-(1→2)-β-D-glucuronide, into a specific triglucuronide with the chemical name luteolin 7-O-[beta-D-glucuronosyl-(1->2)-beta-D-glucuronide]-4'-O-beta-D-glucuronide. The enzyme characterised from the leaves of Secale cereale trans…

Reference excerpt

Luteolin-7-O-diglucuronide 4'-O-glucuronosyltransferase (EC 2.4.1.191) is an enzyme that catalyzes a chemical reaction which converts a luteolin di-glucuronide, luteolin 7-O-(β-D-glucuronosyl-(1→2)-β-D-glucuronide, into a specific triglucuronide with the chemical name luteolin 7-O-[beta-D-glucuronosyl-(1->2)-beta-D-glucuronide]-4'-O-beta-D-glucuronide. The enzyme characterised from the leaves of Secale cereale transfers the third sugar acid from UDP-glucuronate, giving uridine diphosphate (UDP) as a byproduct.

This enzyme belongs to the family of glycosyltransferases, specifically the hexosyltransferases. The systematic name of this enzyme class is UDP-glucuronate:luteolin-7-O-beta-D-diglucuronide 4'-O-glucuronosyltransferase. Other names in common use include uridine diphosphoglucuronate-luteolin 7-O-diglucuronide, glucuronosyltransferase, UDP-glucuronate:luteolin 7-O-diglucuronide-glucuronosyltransferase, UDPglucuronate:luteolin, 7-O-diglucuronide-4'-O-glucuronosyl-transferase, and LDT.

Worked examples

Example 1 — a first encounter with Luteolin-7-O-diglucuronide 4'-O-glucuronosyltransferase

Start with the simplest possible case. Write down what Luteolin-7-O-diglucuronide 4'-O-glucuronosyltransferase 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 Luteolin-7-O-diglucuronide 4'-O-glucuronosyltransferase 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 Luteolin-7-O-diglucuronide 4'-O-glucuronosyltransferase 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 Luteolin-7-O-diglucuronide 4'-O-glucuronosyltransferase

In research: Luteolin-7-O-diglucuronide 4'-O-glucuronosyltransferase 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 Luteolin-7-O-diglucuronide 4'-O-glucuronosyltransferase 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: Luteolin-7-O-diglucuronide 4'-O-glucuronosyltransferase is common in secondary-school and first-year university syllabi. It links to neighbouring topics EC 2.4.1, EC 2.4 stubs, Enzymes of unknown structure, so understanding it makes those chapters shorter.
In everyday life: Look for Luteolin-7-O-diglucuronide 4'-O-glucuronosyltransferase 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.
