Histidinol-phosphatase

Histidinol-phosphatase 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 Histidinol-phosphatase rather than just read about it. In short: The enzyme histidinol-phosphatase (EC 3.1.3.15) catalyzes the reaction The enzyme characterised from Neurospora crassa hydrolyses L-histidinol phosphate to histidinol and orthophosphate. The reaction is part of the biosynthesis of the amino acid histidine.

Reference excerpt

The enzyme histidinol-phosphatase (EC 3.1.3.15) catalyzes the reaction

The enzyme characterised from Neurospora crassa hydrolyses L-histidinol phosphate to histidinol and orthophosphate. The reaction is part of the biosynthesis of the amino acid histidine.

Nomenclature This enzyme is a hydrolase, specifically one acting on phosphoric monoester bonds. The systematic name is L-histidinol-phosphate phosphohydrolase. Other names in common use include histidinol phosphate phosphatase, L-histidinol phosphate phosphatase, histidinolphosphate phosphatase, HPpase, and histidinolphosphatase.

E. coli

In E. coli the enzyme encoded by the gene hisB is a fused imidazoleglycerol-phosphate dehydratase and histidinol-phosphatase.

Worked examples

Example 1 — a first encounter with Histidinol-phosphatase

Start with the simplest possible case. Write down what Histidinol-phosphatase 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 Histidinol-phosphatase 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 Histidinol-phosphatase 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 Histidinol-phosphatase

In research: Histidinol-phosphatase 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 Histidinol-phosphatase 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: Histidinol-phosphatase is common in secondary-school and first-year university syllabi. It links to neighbouring topics EC 3.1.3, Enzymes of known structure, so understanding it makes those chapters shorter.
In everyday life: Look for Histidinol-phosphatase 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.

Frequently asked questions

What is Histidinol-phosphatase in simple terms?

The enzyme histidinol-phosphatase (EC 3.1.3.15) catalyzes the reaction The enzyme characterised from Neurospora crassa hydrolyses L-histidinol phosphate to histidinol and orthophosphate. The reaction is part of the biosynthesis of the amino acid histidine.

Why does Histidinol-phosphatase matter?

Because it connects several engineering ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Histidinol-phosphatase?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
