Hippurate hydrolase

Hippurate hydrolase 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 Hippurate hydrolase rather than just read about it. In short: In enzymology, a hippurate hydrolase (EC 3.5.1.32) is an enzyme that catalyzes the chemical reaction hippurate + H2O ⇌ {\displaystyle \rightleftharpoons } benzoate + glycine Thus, the two substrates of this enzyme are hippurate and H2O, whereas its two products are benzoate and glycine. This enzyme belongs to the family of hydrolases, those acting on carbon-nitrogen bonds other than peptide bonds, specifically in li…

Key takeaways

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

Reference excerpt

In enzymology, a hippurate hydrolase (EC 3.5.1.32) is an enzyme that catalyzes the chemical reaction

hippurate + H2O ⇌ {\displaystyle \rightleftharpoons } benzoate + glycine Thus, the two substrates of this enzyme are hippurate and H2O, whereas its two products are benzoate and glycine. This enzyme belongs to the family of hydrolases, those acting on carbon-nitrogen bonds other than peptide bonds, specifically in linear amides. The systematic name of this enzyme class is N-benzoylamino-acid amidohydrolase. This enzyme participates in phenylalanine metabolism. Hippurate hydrolysis test is used in the presumptive identification of Gardnerella vaginalis, Campylobacter jejuni, Listeria monocytogenes and group B streptococci by detecting the ability of the organism to hydrolyze hippurate.

Worked examples

Example 1 — a first encounter with Hippurate hydrolase

Start with the simplest possible case. Write down what Hippurate hydrolase 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 Hippurate hydrolase 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 Hippurate hydrolase 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 Hippurate hydrolase

In research: Hippurate hydrolase 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 Hippurate hydrolase 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: Hippurate hydrolase is common in secondary-school and first-year university syllabi. It links to neighbouring topics EC 3.5.1, EC 3.5 stubs, Enzymes of unknown structure, so understanding it makes those chapters shorter.
In everyday life: Look for Hippurate hydrolase 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.
