Homoserine O-succinyltransferase

Homoserine O-succinyltransferase 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 Homoserine O-succinyltransferase rather than just read about it. In short: Homoserine O-succinyltransferase (EC 2.3.1.46) is an enzyme that catalyzes the chemical reaction The two substrates of this enzyme characterised from Escherichia coli are homoserine and succinyl-CoA. Its products are O-succinyl-L-homoserine and coenzyme A.

Reference excerpt

Homoserine O-succinyltransferase (EC 2.3.1.46) is an enzyme that catalyzes the chemical reaction

The two substrates of this enzyme characterised from Escherichia coli are homoserine and succinyl-CoA. Its products are O-succinyl-L-homoserine and coenzyme A. This enzyme belongs to the family of transferases, specifically those acyltransferases transferring groups other than aminoacyl groups. The systematic name of this enzyme class is succinyl-CoA:L-homoserine O-succinyltransferase. Other names in common use include homoserine O-transsuccinylase, and homoserine succinyltransferase. It participates in cysteine and methionine metabolism.

Structural studies As of late 2016, three structures have been solved for this class of enzymes, with PDB accession codes PDB: 2GHR, PDB: 2H2W, and PDB: 2VDJ.

Worked examples

Example 1 — a first encounter with Homoserine O-succinyltransferase

Start with the simplest possible case. Write down what Homoserine O-succinyltransferase 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 Homoserine O-succinyltransferase 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 Homoserine O-succinyltransferase 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 Homoserine O-succinyltransferase

In research: Homoserine O-succinyltransferase 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 Homoserine O-succinyltransferase 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: Homoserine O-succinyltransferase is common in secondary-school and first-year university syllabi. It links to neighbouring topics EC 2.3.1, EC 2.3 stubs, Enzymes of known structure, so understanding it makes those chapters shorter.
In everyday life: Look for Homoserine O-succinyltransferase 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.
