Reference excerpt

In enzymology, a phospho-N-acetylmuramoyl-pentapeptide-transferase (EC 2.7.8.13) is an enzyme that catalyzes the chemical reaction

UDP-Mur2Ac(oyl-L-Ala-gamma-D-Glu-L-Lys-D-Ala-D-Ala) + undecaprenyl phosphate ⇌ {\displaystyle \rightleftharpoons } UMP + Mur2Ac(oyl-L-Ala-gamma-D-Glu-L-Lys-D-Ala-D-Ala)-diphosphoundecaprenol Thus, the two substrates of this enzyme are UDP-Mur2Ac(oyl-L-Ala-gamma-D-Glu-L-Lys-D-Ala-D-Ala) and undecaprenyl phosphate, whereas its 2 products are UMP and Mur2Ac(oyl-L-Ala-gamma-D-Glu-L-Lys-D-Ala-D-Ala)-diphosphoundecaprenol. This enzyme participates in peptidoglycan biosynthesis. It can be expressed efficiently by a cell-free protein expression system.

Nomenclature This enzyme belongs to the family of transferases, specifically those transferring non-standard substituted phosphate groups. The systematic name of this enzyme class is UDP-MurAc(oyl-L-Ala-gamma-D-Glu-L-Lys-D-Ala-D-Ala): undecaprenyl-phosphate phospho-N-acetylmuramoyl-pentapeptide-transferase. Other names in common use include translocase I, MraY transferase, UDP-MurNAc-L-Ala-D-gamma-Glu-L-Lys-D-Ala-D-Ala:C55-isoprenoid, alcohol transferase, UDP-MurNAc-Ala-gammaDGlu-Lys-DAla-DAla:undecaprenylphosphate, transferase, phospho-N-acetylmuramoyl pentapeptide translocase, phospho-MurNAc-pentapeptide transferase, phospho-NAc-muramoyl-pentapeptide translocase (UMP), phosphoacetylmuramoylpentapeptide translocase, and phosphoacetylmuramoylpentapeptidetransferase.

Worked examples

Example 1 — a first encounter with Phospho-N-acetylmuramoyl-pentapeptide-transferase

Start with the simplest possible case. Write down what Phospho-N-acetylmuramoyl-pentapeptide-transferase 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 Phospho-N-acetylmuramoyl-pentapeptide-transferase 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 Phospho-N-acetylmuramoyl-pentapeptide-transferase 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 Phospho-N-acetylmuramoyl-pentapeptide-transferase

In research: Phospho-N-acetylmuramoyl-pentapeptide-transferase 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 Phospho-N-acetylmuramoyl-pentapeptide-transferase 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: Phospho-N-acetylmuramoyl-pentapeptide-transferase is common in secondary-school and first-year university syllabi. It links to neighbouring topics EC 2.7.8, EC 2.7 stubs, Enzymes of unknown structure, so understanding it makes those chapters shorter.
In everyday life: Look for Phospho-N-acetylmuramoyl-pentapeptide-transferase 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.
