Trans-cinnamate 4-monooxygenase

Trans-cinnamate 4-monooxygenase 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 Trans-cinnamate 4-monooxygenase rather than just read about it. In short: Trans-cinnamate 4-monooxygenase (EC 1.14.14.91) is an enzyme that catalyzes the chemical reaction The four substrates of this enzyme are cinnamic acid, reduced nicotinamide adenine dinucleotide phosphate (NADPH), oxygen, and a proton. Its products are p-coumaric acid, oxidised NADP+, and water.

Reference excerpt

Trans-cinnamate 4-monooxygenase (EC 1.14.14.91) is an enzyme that catalyzes the chemical reaction

The four substrates of this enzyme are cinnamic acid, reduced nicotinamide adenine dinucleotide phosphate (NADPH), oxygen, and a proton. Its products are p-coumaric acid, oxidised NADP+, and water. It participates in phenylalanine metabolism and phenylpropanoid biosynthesis, especially of flavonoids in plants. The enzyme is a cytochrome P450 protein containing heme. It requires a partner cytochrome P450 reductase for functional expression. This uses nicotinamide adenine dinucleotide phosphate (NADPH).

Nomenclature The systematic name of this enzyme class is trans-cinnamate,NADPH:oxygen oxidoreductase (4-hydroxylating). Other names in common use include:

Worked examples

Example 1 — a first encounter with Trans-cinnamate 4-monooxygenase

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

In research: Trans-cinnamate 4-monooxygenase 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 Trans-cinnamate 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: Trans-cinnamate 4-monooxygenase is common in secondary-school and first-year university syllabi. It links to neighbouring topics EC 1.14.13 stubs, EC 1.14.14, Enzymes of unknown structure, so understanding it makes those chapters shorter.
In everyday life: Look for Trans-cinnamate 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.
