Gibberellin 3beta-dioxygenase

Gibberellin 3beta-dioxygenase 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 Gibberellin 3beta-dioxygenase rather than just read about it. In short: In enzymology, a gibberellin 3beta-dioxygenase (EC 1.14.11.15) is an enzyme that catalyzes the chemical reaction gibberellin 20 + 2-oxoglutarate + O2 ⇌ {\displaystyle \rightleftharpoons } gibberellin 1 + succinate + CO2 The 3 substrates of this enzyme are gibberellin 20, 2-oxoglutarate, and O2, whereas its 3 products are gibberellin 1, succinate, and CO2. This enzyme belongs to the family of oxidoreductases, specifi…

Reference excerpt

In enzymology, a gibberellin 3beta-dioxygenase (EC 1.14.11.15) is an enzyme that catalyzes the chemical reaction

gibberellin 20 + 2-oxoglutarate + O2 ⇌ {\displaystyle \rightleftharpoons } gibberellin 1 + succinate + CO2 The 3 substrates of this enzyme are gibberellin 20, 2-oxoglutarate, and O2, whereas its 3 products are gibberellin 1, succinate, and CO2. This enzyme belongs to the family of oxidoreductases, specifically those acting on paired donors, with O2 as the oxidant. The oxygen incorporated need not be derived from O2 with 2-oxoglutarate as one donor, and one atom of oxygen is incorporated into each donor. The systematic name of this enzyme class is (gibberellin-20), 2-oxoglutarate: oxygen oxidoreductase (3beta-hydroxylating). Other names in common use include gibberellin 3beta-hydroxylase, (gibberrellin-20), 2-oxoglutarate: oxygen oxidoreductase and (3beta-hydroxylating). This enzyme participates in diterpenoid biosynthesis. It has 2 cofactors: iron and Ascorbate.

Worked examples

Example 1 — a first encounter with Gibberellin 3beta-dioxygenase

Start with the simplest possible case. Write down what Gibberellin 3beta-dioxygenase 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 Gibberellin 3beta-dioxygenase 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 Gibberellin 3beta-dioxygenase 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 Gibberellin 3beta-dioxygenase

In research: Gibberellin 3beta-dioxygenase 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 Gibberellin 3beta-dioxygenase 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: Gibberellin 3beta-dioxygenase is common in secondary-school and first-year university syllabi. It links to neighbouring topics Ascorbate enzymes, EC 1.14.11, EC 1.14 stubs, so understanding it makes those chapters shorter.
In everyday life: Look for Gibberellin 3beta-dioxygenase 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.
