Phenol 2-monooxygenase

Phenol 2-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 Phenol 2-monooxygenase rather than just read about it. In short: Phenol 2-monooxygenase (EC 1.14.13.7) is an enzyme that catalyzes the chemical reaction The four substrates of this enzyme are phenol, reduced nicotinamide adenine dinucleotide phosphate (NADPH), oxygen and a proton. Its products are catechol, oxidised NADP+, and water.

Key takeaways

Phenol 2-monooxygenase belongs to biology; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Phenol 2-monooxygenase to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Phenol 2-monooxygenase from memory before moving on to harder problems.

Reference excerpt

Phenol 2-monooxygenase (EC 1.14.13.7) is an enzyme that catalyzes the chemical reaction

The four substrates of this enzyme are phenol, reduced nicotinamide adenine dinucleotide phosphate (NADPH), oxygen and a proton. Its products are catechol, oxidised NADP+, and water. 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 phenol,NADPH:oxygen oxidoreductase (2-hydroxylating). Other names in common use include phenol hydroxylase, and phenol o-hydroxylase. It uses flavin adenine dinucleotide as a cofactor. The enzyme from Trichosporon cutaneum can hydroxylate a range of phenols.

Structural studies As of late 2007, 3 structures have been solved for this class of enzymes, with PDB accession codes PDB: 1FOH, PDB: 1HQI, and PDB: 1PN0.

Worked examples

Example 1 — a first encounter with Phenol 2-monooxygenase

Start with the simplest possible case. Write down what Phenol 2-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 Phenol 2-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 Phenol 2-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 Phenol 2-monooxygenase

In research: Phenol 2-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 Phenol 2-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: Phenol 2-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 known structure, so understanding it makes those chapters shorter.
In everyday life: Look for Phenol 2-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.
