Undecaprenyl-phosphate mannosyltransferase

Undecaprenyl-phosphate mannosyltransferase 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 Undecaprenyl-phosphate mannosyltransferase rather than just read about it. In short: In enzymology, an undecaprenyl-phosphate mannosyltransferase (EC 2.4.1.54) is an enzyme that catalyzes the chemical reaction GDP-mannose + undecaprenyl phosphate ⇌ {\displaystyle \rightleftharpoons } GDP + D-mannosyl-1-phosphoundecaprenol Thus, the two substrates of this enzyme are GDP-mannose and undecaprenyl phosphate, whereas its two products are GDP and D-mannosyl-1-phosphoundecaprenol. This enzyme belongs to th…

Reference excerpt

In enzymology, an undecaprenyl-phosphate mannosyltransferase (EC 2.4.1.54) is an enzyme that catalyzes the chemical reaction

GDP-mannose + undecaprenyl phosphate ⇌ {\displaystyle \rightleftharpoons } GDP + D-mannosyl-1-phosphoundecaprenol Thus, the two substrates of this enzyme are GDP-mannose and undecaprenyl phosphate, whereas its two products are GDP and D-mannosyl-1-phosphoundecaprenol. This enzyme belongs to the family of glycosyltransferases, specifically the hexosyltransferases. The systematic name of this enzyme class is GDP-mannose:undecaprenyl-phosphate D-mannosyltransferase. Other names in common use include guanosine diphosphomannose-undecaprenyl phosphate, mannosyltransferase, GDP mannose-undecaprenyl phosphate mannosyltransferase, and GDP-D-mannose:lipid phosphate transmannosylase. It employs one cofactor, phosphatidylglycerol. Sources of this enzyme includes Micrococcus luteus, Phaseolus aureus, Mycobacterium smegmatis and cotton fibers.

Worked examples

Example 1 — a first encounter with Undecaprenyl-phosphate mannosyltransferase

Start with the simplest possible case. Write down what Undecaprenyl-phosphate mannosyltransferase 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 Undecaprenyl-phosphate mannosyltransferase 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 Undecaprenyl-phosphate mannosyltransferase 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 Undecaprenyl-phosphate mannosyltransferase

In research: Undecaprenyl-phosphate mannosyltransferase 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 Undecaprenyl-phosphate mannosyltransferase 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: Undecaprenyl-phosphate mannosyltransferase is common in secondary-school and first-year university syllabi. It links to neighbouring topics EC 2.4.1, EC 2.4 stubs, Enzymes of unknown structure, so understanding it makes those chapters shorter.
In everyday life: Look for Undecaprenyl-phosphate mannosyltransferase 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.
