Glutamate synthase (ferredoxin)

Glutamate synthase (ferredoxin) is a biology 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 Glutamate synthase (ferredoxin) rather than just read about it. In short: In enzymology, glutamate synthase (ferredoxin) (EC 1.4.7.1) is an enzyme that catalyzes the chemical reaction The two substrates of this enzyme are L-glutamic acid and oxidised ferredoxin. Its products are L-glutamine, α-ketoglutaric acid, reduced ferredoxin, and two protons.

Key takeaways

Glutamate synthase (ferredoxin) belongs to biology; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Glutamate synthase (ferredoxin) to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Glutamate synthase (ferredoxin) from memory before moving on to harder problems.

Reference excerpt

In enzymology, glutamate synthase (ferredoxin) (EC 1.4.7.1) is an enzyme that catalyzes the chemical reaction

The two substrates of this enzyme are L-glutamic acid and oxidised ferredoxin. Its products are L-glutamine, α-ketoglutaric acid, reduced ferredoxin, and two protons.

Classification This enzyme belongs to the family of oxidoreductases, specifically those acting on the CH-NH2 group of donors with an iron-sulfur protein as acceptor.

Nomenclature The systematic name of this enzyme class is L-glutamate:ferredoxin oxidoreductase (transaminating). Other names in common use include:

ferredoxin-dependent glutamate synthase, ferredoxin-glutamate synthase, glutamate synthase (ferredoxin-dependent), and ferredoxin-glutamine oxoglutarate aminotransferase (Fd-GOGAT).

Biological role This enzyme participates in nitrogen metabolism. It has 5 cofactors: flavin adenine dinucleotide, iron, sulfur, iron-sulfur, and flavoprotein.

Worked examples

Example 1 — a first encounter with Glutamate synthase (ferredoxin)

Start with the simplest possible case. Write down what Glutamate synthase (ferredoxin) claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In biology, 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 Glutamate synthase (ferredoxin) 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 Glutamate synthase (ferredoxin) 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 Glutamate synthase (ferredoxin)

In research: Glutamate synthase (ferredoxin) appears in biology 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 Glutamate synthase (ferredoxin) 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: Glutamate synthase (ferredoxin) is common in secondary-school and first-year university syllabi. It links to neighbouring topics EC 1.4.7, Enzymes of known structure, Flavoproteins, so understanding it makes those chapters shorter.
In everyday life: Look for Glutamate synthase (ferredoxin) 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.
