L,L-diaminopimelate aminotransferase

L,L-diaminopimelate aminotransferase 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 L,L-diaminopimelate aminotransferase rather than just read about it. In short: L,L-diaminopimelate aminotransferase (EC 2.6.1.83) is a pyridoxal phosphate-dependent enzyme that catalyzes the chemical reaction The three substrates of this enzyme characterised from plants are (S)-2,3,4,5-tetrahydrodipicolinic acid (1), L-glutamic acid, and water. Its products are (S,S)-2,6-diaminopimelic acid a.k.a.

Key takeaways

L,L-diaminopimelate aminotransferase belongs to engineering; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect L,L-diaminopimelate aminotransferase to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of L,L-diaminopimelate aminotransferase from memory before moving on to harder problems.

Reference excerpt

L,L-diaminopimelate aminotransferase (EC 2.6.1.83) is a pyridoxal phosphate-dependent enzyme that catalyzes the chemical reaction

The three substrates of this enzyme characterised from plants are (S)-2,3,4,5-tetrahydrodipicolinic acid (1), L-glutamic acid, and water. Its products are (S,S)-2,6-diaminopimelic acid a.k.a. L,L-diaminopimelic acid (2) and α-ketoglutaric acid. The product (2) goes on in a biosynthetic pathway leading to the amino acid lysine. This enzyme is a transferases, specifically a transaminase, which transfer nitrogenous groups. The systematic name of this enzyme class is LL-2,6-diaminoheptanedioate:2-oxoglutarate aminotransferase. Other names in common use include LL-diaminopimelate transaminase, LL-DAP aminotransferase, and LL-DAP-AT.

Structural studies As of late 2007, two structures have been solved for this class of enzymes, with PDB accession codes PDB: 2Z1Z and PDB: 2Z20.

Worked examples

Example 1 — a first encounter with L,L-diaminopimelate aminotransferase

Start with the simplest possible case. Write down what L,L-diaminopimelate aminotransferase 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 L,L-diaminopimelate aminotransferase 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 L,L-diaminopimelate aminotransferase 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 L,L-diaminopimelate aminotransferase

In research: L,L-diaminopimelate aminotransferase 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 L,L-diaminopimelate aminotransferase 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: L,L-diaminopimelate aminotransferase is common in secondary-school and first-year university syllabi. It links to neighbouring topics EC 2.6.1, EC 2.6 stubs, Enzymes of known structure, so understanding it makes those chapters shorter.
In everyday life: Look for L,L-diaminopimelate aminotransferase 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.
