Isoflavone 2'-hydroxylase

Isoflavone 2'-hydroxylase 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 Isoflavone 2'-hydroxylase rather than just read about it. In short: In enzymology, an isoflavone 2'-hydroxylase (EC 1.14.14.90, Formerly EC 1.14.13.89) is an enzyme that catalyzes the chemical reaction an isoflavone + NADPH + H+ + O2 ⇌ {\displaystyle \rightleftharpoons } a 2'-hydroxyisoflavone + NADP+ + H2O The 4 substrates of this enzyme are isoflavone, NADPH, H+, and O2, whereas its 3 products are 2'-hydroxyisoflavone, NADP+, and H2O. This enzyme belongs to the family of oxidoredu…

Key takeaways

Isoflavone 2'-hydroxylase belongs to engineering; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Isoflavone 2'-hydroxylase to a quantity you can measure, compute or draw — that is where exam questions come from.

Reference excerpt

In enzymology, an isoflavone 2'-hydroxylase (EC 1.14.14.90, Formerly EC 1.14.13.89) is an enzyme that catalyzes the chemical reaction

an isoflavone + NADPH + H+ + O2 ⇌ {\displaystyle \rightleftharpoons } a 2'-hydroxyisoflavone + NADP+ + H2O The 4 substrates of this enzyme are isoflavone, NADPH, H+, and O2, whereas its 3 products are 2'-hydroxyisoflavone, NADP+, and H2O. This enzyme belongs to the family of oxidoreductases, specifically those acting on paired donors, with O2 as oxidant and incorporation or reduction of oxygen. The oxygen incorporated need not be derived from O2 with NADH or NADPH as one donor, and incorporation of one atom o oxygen into the other donor. The systematic name of this enzyme class is isoflavone,NADPH:oxygen oxidoreductase (2'-hydroxylating). Other names in common use include isoflavone 2'-monooxygenase, CYP81E1, and CYP Ge-3. This enzyme participates in isoflavonoid biosynthesis.

Worked examples

Example 1 — a first encounter with Isoflavone 2'-hydroxylase

Start with the simplest possible case. Write down what Isoflavone 2'-hydroxylase 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 Isoflavone 2'-hydroxylase 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 Isoflavone 2'-hydroxylase 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 Isoflavone 2'-hydroxylase

In research: Isoflavone 2'-hydroxylase 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 Isoflavone 2'-hydroxylase 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: Isoflavone 2'-hydroxylase 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 Isoflavone 2'-hydroxylase 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.
