Succinate-semialdehyde dehydrogenase

Succinate-semialdehyde dehydrogenase 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-semialdehyde dehydrogenase rather than just read about it. In short: In enzymology, succinate-semialdehyde dehydrogenase (SSADH) (EC 1.2.1.24) is an enzyme that catalyzes the chemical reaction The three substrates of this enzyme are succinic semialdehyde, oxidised nicotinamide adenine dinucleotide (NAD+), and water. Its products are succinic acid, reduced NADH, and a proton.

Reference excerpt

In enzymology, succinate-semialdehyde dehydrogenase (SSADH) (EC 1.2.1.24) is an enzyme that catalyzes the chemical reaction

The three substrates of this enzyme are succinic semialdehyde, oxidised nicotinamide adenine dinucleotide (NAD+), and water. Its products are succinic acid, reduced NADH, and a proton. This enzyme belongs to the family of oxidoreductases, specifically those acting on the aldehyde or oxo group of donor with NAD+ or NADP+ as acceptor. The systematic name of this enzyme class is succinate-semialdehyde:NAD+ oxidoreductase. Other names in common use include succinate semialdehyde dehydrogenase, succinic semialdehyde dehydrogenase, succinyl semialdehyde dehydrogenase, and succinate semialdehyde:NAD+ oxidoreductase. This enzyme participates in glutamate and butyrate metabolism. Succinate-semialdehyde dehydrogenase is found in organisms ranging across the tree of life from bacteria to humans. It is important in the degradation of γ-aminobutyric acid in humans, and deficiency of the enzyme causes serious health effects (succinic semialdehyde dehydrogenase deficiency). In bacteria, the enzyme is also involved in γ-aminobutyric acid degradation, but can be recruited to facilitate other functions, such as converting succinate-semialdehyde formed during fission of the pyridine ring to succinic acid for entry into the Krebs Cycle.

Worked examples

Example 1 — a first encounter with Succinate-semialdehyde dehydrogenase

Start with the simplest possible case. Write down what Succinate-semialdehyde dehydrogenase 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-semialdehyde dehydrogenase 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-semialdehyde dehydrogenase 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-semialdehyde dehydrogenase

In research: Succinate-semialdehyde dehydrogenase 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-semialdehyde dehydrogenase 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-semialdehyde dehydrogenase is common in secondary-school and first-year university syllabi. It links to neighbouring topics EC 1.2.1, EC 1.2 stubs, Enzymes of unknown structure, so understanding it makes those chapters shorter.
In everyday life: Look for Succinate-semialdehyde dehydrogenase 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.
