Unspecific monooxygenase

Unspecific 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 Unspecific monooxygenase rather than just read about it. In short: In enzymology, an unspecific monooxygenase (EC 1.14.14.1) is an enzyme that catalyzes the chemical reaction RH + reduced flavoprotein + O2 ⇌ {\displaystyle \rightleftharpoons } ROH + oxidized flavoprotein + H2O The 3 substrates of this enzyme are RH (reduced substrate), reduced flavoprotein, and O2, whereas its 3 products are ROH (oxidized substrate), oxidized flavoprotein, and H2O. This enzyme belongs to the family…

Reference excerpt

In enzymology, an unspecific monooxygenase (EC 1.14.14.1) is an enzyme that catalyzes the chemical reaction

RH + reduced flavoprotein + O2 ⇌ {\displaystyle \rightleftharpoons } ROH + oxidized flavoprotein + H2O The 3 substrates of this enzyme are RH (reduced substrate), reduced flavoprotein, and O2, whereas its 3 products are ROH (oxidized substrate), oxidized flavoprotein, 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 reduced flavin or flavoprotein as one donor, and incorporation of one atom of oxygen into the other donor. The systematic name of this enzyme class is substrate,reduced-flavoprotein:oxygen oxidoreductase (RH-hydroxylating or -epoxidizing). Other names in common use include microsomal monooxygenase, xenobiotic monooxygenase, aryl-4-monooxygenase, aryl hydrocarbon hydroxylase, microsomal P-450, flavoprotein-linked monooxygenase, and flavoprotein monooxygenase. This enzyme participates in 7 metabolic pathways: fatty acid metabolism, androgen and estrogen metabolism, gamma-hexachlorocyclohexane degradation, tryptophan metabolism, arachidonic acid metabolism, linoleic acid metabolism, and metabolism of xenobiotics by cytochrome p450. It employs one cofactor, heme.

Structural studies As of late 2007, 53 structures have been solved for this class of enzymes, with PDB accession codes PDB: 1BU7, PDB: 1BVY, PDB: 1DT6, PDB: 1FAG, PDB: 1FAH, PDB: 1JME, PDB: 1JPZ, PDB: 1N6B, PDB: 1NR6, PDB: 1OG2, PDB: 1OG5, PDB: 1P0V, PDB: 1P0W, PDB: 1P0X, PDB: 1PO5, PDB: 1PQ2, PDB: 1R9O, PDB: 1SMI, PDB: 1SMJ, PDB: 1SUO, PDB: 1TQN, PDB: 1W0E, PDB: 1W0F, PDB: 1W0G, PDB: 1YQO, PDB: 1YQP, PDB: 1Z10, PDB: 1Z11, PDB: 1ZO4, PDB: 1ZO9, PDB: 1ZOA, PDB: 2BDM, PDB: 2BMH, PDB: 2F9Q, PDB: 2FDU, PDB: 2FDV, PDB: 2FDW, PDB: 2FDY, PDB: 2HI4, PDB: 2HPD, PDB: 2IJ2, PDB: 2IJ3, PDB: 2IJ4, PDB: 2J0D, PDB: 2J1M, PDB: 2J4S, PDB: 2NNB, PDB: 2P85, PDB: 2PG5, PDB: 2PG6, PDB: 2PG7, PDB: 2UWH, and PDB: 2V0M.

Worked examples

Example 1 — a first encounter with Unspecific monooxygenase

Start with the simplest possible case. Write down what Unspecific 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 Unspecific 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 Unspecific 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 Unspecific monooxygenase

In research: Unspecific 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 Unspecific 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: Unspecific monooxygenase is common in secondary-school and first-year university syllabi. It links to neighbouring topics EC 1.14.14, EC 1.14 stubs, Enzymes of known structure, so understanding it makes those chapters shorter.
In everyday life: Look for Unspecific 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.
