S-(hydroxymethyl)glutathione dehydrogenase

S-(hydroxymethyl)glutathione 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 S-(hydroxymethyl)glutathione dehydrogenase rather than just read about it. In short: In enzymology, S-(hydroxymethyl)glutathione dehydrogenase (EC 1.1.1.284) is an enzyme that catalyzes the chemical reaction The two substrates of this enzyme are S-(hydroxymethyl)glutathione and oxidised nicotinamide adenine dinucleotide (NAD+). Its products are S-formylglutathione, reduced NADH, and a proton.

Key takeaways

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

Reference excerpt

In enzymology, S-(hydroxymethyl)glutathione dehydrogenase (EC 1.1.1.284) is an enzyme that catalyzes the chemical reaction

The two substrates of this enzyme are S-(hydroxymethyl)glutathione and oxidised nicotinamide adenine dinucleotide (NAD+). Its products are S-formylglutathione, reduced NADH, and a proton. The enzyme can also use the alternative cofactor, nicotinamide adenine dinucleotide phosphate. This enzyme belongs to the family of oxidoreductases, specifically those acting on the CH-OH group of donor with NAD+ or NADP+ as acceptor. The systematic name of this enzyme class is S-(hydroxymethyl)glutathione:NAD+ oxidoreductase. Other names in common use include NAD-linked formaldehyde dehydrogenase (incorrect), formaldehyde dehydrogenase (incorrect), formic dehydrogenase (incorrect), class III alcohol dehydrogenase, ADH3, &chi, -ADH, FDH (incorrect), formaldehyde dehydrogenase (glutathione) (incorrect), GS-FDH (incorrect), glutathione-dependent formaldehyde dehydrogenase (incorrect), NAD-dependent formaldehyde dehydrogenase, GD-FALDH, and NAD- and glutathione-dependent formaldehyde dehydrogenase. This enzyme participates in methane metabolism.

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

Worked examples

Example 1 — a first encounter with S-(hydroxymethyl)glutathione dehydrogenase

Start with the simplest possible case. Write down what S-(hydroxymethyl)glutathione 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 S-(hydroxymethyl)glutathione 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 S-(hydroxymethyl)glutathione 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 S-(hydroxymethyl)glutathione dehydrogenase

In research: S-(hydroxymethyl)glutathione 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 S-(hydroxymethyl)glutathione 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: S-(hydroxymethyl)glutathione dehydrogenase is common in secondary-school and first-year university syllabi. It links to neighbouring topics EC 1.1.1, EC 1.1.1 stubs, Enzymes of known structure, so understanding it makes those chapters shorter.
In everyday life: Look for S-(hydroxymethyl)glutathione 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.
