Succinate—CoA ligase (ADP-forming)

Succinate—CoA ligase (ADP-forming) 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 Succinate—CoA ligase (ADP-forming) rather than just read about it. In short: In enzymology, a succinate-CoA ligase (ADP-forming) (EC 6.2.1.5) is an enzyme that catalyzes the chemical reaction ATP + succinate + CoA ⇌ {\displaystyle \rightleftharpoons } ADP + phosphate + succinyl-CoA The 3 substrates of this enzyme are ATP, succinate, and CoA, whereas its 3 products are ADP, phosphate, and succinyl-CoA. This enzyme belongs to the family of ligases, specifically those forming carbon-sulfur bond…

Reference excerpt

In enzymology, a succinate-CoA ligase (ADP-forming) (EC 6.2.1.5) is an enzyme that catalyzes the chemical reaction

ATP + succinate + CoA ⇌ {\displaystyle \rightleftharpoons } ADP + phosphate + succinyl-CoA The 3 substrates of this enzyme are ATP, succinate, and CoA, whereas its 3 products are ADP, phosphate, and succinyl-CoA. This enzyme belongs to the family of ligases, specifically those forming carbon-sulfur bonds as acid-thiol ligases. The systematic name of this enzyme class is succinate:CoA ligase (ADP-forming). Other names in common use include succinyl-CoA synthetase (ADP-forming), succinic thiokinase, succinate thiokinase, succinyl-CoA synthetase, succinyl coenzyme A synthetase (adenosine diphosphate-forming), succinyl coenzyme A synthetase, A-STK (adenin nucleotide-linked succinate thiokinase), STK, and A-SCS. This enzyme participates in 4 metabolic pathways: Citric acid cycle, propanoate metabolism, c5-branched dibasic acid metabolism, and reductive carboxylate cycle (CO2 fixation).

Structural studies As of late 2007, 12 structures have been solved for this class of enzymes, with PDB accession codes PDB: 1CQI, PDB: 1CQJ, PDB: 1JKJ, PDB: 1JLL, PDB: 1OI7, PDB: 1SCU, PDB: 2NU6, PDB: 2NU7, PDB: 2NU8, PDB: 2NU9, PDB: 2NUA, and PDB: 2SCU.

Worked examples

Example 1 — a first encounter with Succinate—CoA ligase (ADP-forming)

Start with the simplest possible case. Write down what Succinate—CoA ligase (ADP-forming) 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 Succinate—CoA ligase (ADP-forming) 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 Succinate—CoA ligase (ADP-forming) 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 Succinate—CoA ligase (ADP-forming)

In research: Succinate—CoA ligase (ADP-forming) 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 Succinate—CoA ligase (ADP-forming) 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: Succinate—CoA ligase (ADP-forming) is common in secondary-school and first-year university syllabi. It links to neighbouring topics EC 6.2.1, Enzymes of known structure, Ligase stubs, so understanding it makes those chapters shorter.
In everyday life: Look for Succinate—CoA ligase (ADP-forming) 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.
