Gibberellin-44 dioxygenase

Gibberellin-44 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-44 dioxygenase rather than just read about it. In short: In enzymology, a gibberellin-44 dioxygenase (EC 1.14.11.12) is an enzyme that catalyzes the chemical reaction gibberellin 44 + 2-oxoglutarate + O2 ⇌ {\displaystyle \rightleftharpoons } gibberellin 19 + succinate + CO2 The 3 substrates of this enzyme are gibberellin 44, 2-oxoglutarate, and O2, whereas its 3 products are gibberellin 19, succinate, and CO2. This enzyme belongs to the family of oxidoreductases, specific…

Reference excerpt

In enzymology, a gibberellin-44 dioxygenase (EC 1.14.11.12) is an enzyme that catalyzes the chemical reaction

gibberellin 44 + 2-oxoglutarate + O2 ⇌ {\displaystyle \rightleftharpoons } gibberellin 19 + succinate + CO2 The 3 substrates of this enzyme are gibberellin 44, 2-oxoglutarate, and O2, whereas its 3 products are gibberellin 19, succinate, and CO2. This enzyme belongs to the family of oxidoreductases, specifically those acting on paired donors, with O2 as oxidant and incorporation or reduction of oxygen. The oxygen incorporated need not be derived from O2 with 2-oxoglutarate as one donor, and incorporation of one atom o oxygen into each donor. The systematic name of this enzyme class is (gibberellin-44),2-oxoglutarate:oxygen oxidoreductase. Other names in common use include oxygenase, gibberellin A44 oxidase, and (gibberellin-44), 2-oxoglutarate:oxygen oxidoreductase. This enzyme participates in diterpenoid biosynthesis. It employs one cofactor, iron.

Worked examples

Example 1 — a first encounter with Gibberellin-44 dioxygenase

Start with the simplest possible case. Write down what Gibberellin-44 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-44 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-44 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-44 dioxygenase

In research: Gibberellin-44 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-44 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-44 dioxygenase is common in secondary-school and first-year university syllabi. It links to neighbouring topics EC 1.14.11, EC 1.14 stubs, Enzymes of unknown structure, so understanding it makes those chapters shorter.
In everyday life: Look for Gibberellin-44 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.
