Imidazoleacetate 4-monooxygenase

Imidazoleacetate 4-monooxygenase 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 Imidazoleacetate 4-monooxygenase rather than just read about it. In short: In enzymology, an imidazoleacetate 4-monooxygenase (EC 1.14.13.5) is an enzyme that catalyzes the chemical reaction 4-imidazoleacetate + NADH + H+ + O2 ⇌ {\displaystyle \rightleftharpoons } 5-hydroxy-4-imidazoleacetate + NAD+ + H2O The 4 substrates of this enzyme are 4-imidazoleacetate, NADH, H+, and O2, whereas its 3 products are 5-hydroxy-4-imidazoleacetate, NAD+, and H2O. The enzyme is a flavin-containing monooxy…

Reference excerpt

In enzymology, an imidazoleacetate 4-monooxygenase (EC 1.14.13.5) is an enzyme that catalyzes the chemical reaction

4-imidazoleacetate + NADH + H+ + O2 ⇌ {\displaystyle \rightleftharpoons } 5-hydroxy-4-imidazoleacetate + NAD+ + H2O The 4 substrates of this enzyme are 4-imidazoleacetate, NADH, H+, and O2, whereas its 3 products are 5-hydroxy-4-imidazoleacetate, NAD+, and H2O. The enzyme is a flavin-containing monooxygenase that uses molecular oxygen as oxidant and incorporates one of its atoms into the starting material. The systematic name of this enzyme class is 4-imidazoleacetate,NADH:oxygen oxidoreductase (5-hydroxylating). Other names in common use include imidazoleacetic hydroxylase, imidazoleacetate hydroxylase, and imidazoleacetic monooxygenase. This enzyme participates in histidine metabolism. It employs one cofactor, FAD.

Worked examples

Example 1 — a first encounter with Imidazoleacetate 4-monooxygenase

Start with the simplest possible case. Write down what Imidazoleacetate 4-monooxygenase 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 Imidazoleacetate 4-monooxygenase 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 Imidazoleacetate 4-monooxygenase 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 Imidazoleacetate 4-monooxygenase

In research: Imidazoleacetate 4-monooxygenase 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 Imidazoleacetate 4-monooxygenase 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: Imidazoleacetate 4-monooxygenase is common in secondary-school and first-year university syllabi. It links to neighbouring topics EC 1.14.13, EC 1.14.13 stubs, Enzymes of unknown structure, so understanding it makes those chapters shorter.
In everyday life: Look for Imidazoleacetate 4-monooxygenase 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.
