Phthalate 4,5-cis-dihydrodiol dehydrogenase

Phthalate 4,5-cis-dihydrodiol dehydrogenase 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 Phthalate 4,5-cis-dihydrodiol dehydrogenase rather than just read about it. In short: In enzymology, phthalate 4,5-cis-dihydrodiol dehydrogenase (EC 1.3.1.64) is an enzyme that catalyzes the chemical reaction The two substrates of this enzyme are cis-4,5-dihydroxycyclohexa-2,6-diene-1,2-dicarboxylic acid and oxidised nicotinamide adenine dinucleotide (NAD+). Its products are 4,5-dihydroxyphthalic acid, reduced NADH, and a proton.

Reference excerpt

In enzymology, phthalate 4,5-cis-dihydrodiol dehydrogenase (EC 1.3.1.64) is an enzyme that catalyzes the chemical reaction

The two substrates of this enzyme are cis-4,5-dihydroxycyclohexa-2,6-diene-1,2-dicarboxylic acid and oxidised nicotinamide adenine dinucleotide (NAD+). Its products are 4,5-dihydroxyphthalic acid, reduced NADH, and a proton. This enzyme belongs to the family of oxidoreductases, specifically those acting on the CH-CH group of donor with NAD+ or NADP+ as acceptor. The systematic name of this enzyme class is cis-4,5-dihydroxycyclohexa-1(6),2-diene-1,2-dicarboxylate:NAD+ oxidoreductase. This enzyme participates in 2,4-dichlorobenzoate degradation.

Worked examples

Example 1 — a first encounter with Phthalate 4,5-cis-dihydrodiol dehydrogenase

Start with the simplest possible case. Write down what Phthalate 4,5-cis-dihydrodiol dehydrogenase 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 Phthalate 4,5-cis-dihydrodiol dehydrogenase 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 Phthalate 4,5-cis-dihydrodiol dehydrogenase 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 Phthalate 4,5-cis-dihydrodiol dehydrogenase

In research: Phthalate 4,5-cis-dihydrodiol dehydrogenase 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 Phthalate 4,5-cis-dihydrodiol dehydrogenase 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: Phthalate 4,5-cis-dihydrodiol dehydrogenase is common in secondary-school and first-year university syllabi. It links to neighbouring topics EC 1.3.1, EC 1.3 stubs, Enzymes of unknown structure, so understanding it makes those chapters shorter.
In everyday life: Look for Phthalate 4,5-cis-dihydrodiol dehydrogenase 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.
