Lysine 2-monooxygenase

Lysine 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 Lysine 2-monooxygenase rather than just read about it. In short: Lysine 2-monooxygenase (EC 1.13.12.2) is an enzyme that catalyzes the chemical reaction The two substrates of this enzyme are L-lysine and oxygen. Its products are 5-aminopentanamide, carbon dioxide, and water.

Reference excerpt

Lysine 2-monooxygenase (EC 1.13.12.2) is an enzyme that catalyzes the chemical reaction

The two substrates of this enzyme are L-lysine and oxygen. Its products are 5-aminopentanamide, carbon dioxide, and water. This enzyme belongs to the family of oxidoreductases, specifically those acting on single donors with O2 as oxidant and incorporation of two atoms of oxygen into the substrate (oxygenases). The oxygen incorporated need not be derived from O with incorporation of one atom of oxygen (internal monooxygenases o internal mixed-function oxidases). The systematic name of this enzyme class is L-lysine:oxygen 2-oxidoreductase (decarboxylating). Other names in common use include lysine oxygenase, lysine monooxygenase, and L-lysine-2-monooxygenase. This enzyme participates in lysine degradation. It employs one cofactor, flavin adenine dinucleotide.

Worked examples

Example 1 — a first encounter with Lysine 2-monooxygenase

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

In research: Lysine 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 Lysine 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: Lysine 2-monooxygenase is common in secondary-school and first-year university syllabi. It links to neighbouring topics EC 1.13.12, Enzymes of unknown structure, Flavoproteins, so understanding it makes those chapters shorter.
In everyday life: Look for Lysine 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.
