N-carbamoyl-L-amino-acid hydrolase

N-carbamoyl-L-amino-acid hydrolase is a chemistry 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 N-carbamoyl-L-amino-acid hydrolase rather than just read about it. In short: In enzymology, a N-carbamoyl-L-amino-acid hydrolase (EC 3.5.1.87) is an enzyme that catalyzes the chemical reaction N-carbamoyl-L-2-amino acid (a 2-ureido carboxylate) + H2O ⇌ {\displaystyle \rightleftharpoons } L-2-amino acid + NH3 + CO2 Thus, the two substrates of this enzyme are N-carbamoyl-L-2-amino acid and H2O, whereas its 3 products are L-2-amino acid, NH3, and CO2. This enzyme belongs to the subfamily of hyd…

Reference excerpt

In enzymology, a N-carbamoyl-L-amino-acid hydrolase (EC 3.5.1.87) is an enzyme that catalyzes the chemical reaction

N-carbamoyl-L-2-amino acid (a 2-ureido carboxylate) + H2O ⇌ {\displaystyle \rightleftharpoons } L-2-amino acid + NH3 + CO2 Thus, the two substrates of this enzyme are N-carbamoyl-L-2-amino acid and H2O, whereas its 3 products are L-2-amino acid, NH3, and CO2. This enzyme belongs to the subfamily of hydrolases which act on carbon-nitrogen bonds other than peptide bonds, specifically in linear amides. The systematic name of this enzyme class is N-carbamoyl-L-amino acid amidohydrolase.

Worked examples

Example 1 — a first encounter with N-carbamoyl-L-amino-acid hydrolase

Start with the simplest possible case. Write down what N-carbamoyl-L-amino-acid hydrolase claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In chemistry, 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 N-carbamoyl-L-amino-acid 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 N-carbamoyl-L-amino-acid 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 N-carbamoyl-L-amino-acid hydrolase

In research: N-carbamoyl-L-amino-acid hydrolase appears in chemistry 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 N-carbamoyl-L-amino-acid 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: N-carbamoyl-L-amino-acid 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 N-carbamoyl-L-amino-acid 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.
