Proteopedia

Proteopedia is a biology 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 Proteopedia rather than just read about it. In short: Proteopedia is a wiki, 3D encyclopedia of proteins and other molecules. Website The site contains a page for all of the entries in the Protein Data Bank (PDB), as well as pages that are more descriptive of protein structures in general such as acetylcholinesterase, hemoglobin, and the photosystem II with a Jmol view that highlights functional sites and ligands.

Key takeaways

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

Reference excerpt

Proteopedia is a wiki, 3D encyclopedia of proteins and other molecules.

Website The site contains a page for all of the entries in the Protein Data Bank (PDB), as well as pages that are more descriptive of protein structures in general such as acetylcholinesterase, hemoglobin, and the photosystem II with a Jmol view that highlights functional sites and ligands. It employs a scene-authoring tool so that users do not have to learn JSmol script language to create customized molecular scenes. Custom scenes are easily attached to "green links" in descriptive text that display those scenes in JSmol. A web browser is all that is needed to access the site and the 3D information; no viewers are required to be installed. Proteopedia was the winner of the 2010 award for the best website by The Scientist magazine.

Worked examples

Example 1 — a first encounter with Proteopedia

Start with the simplest possible case. Write down what Proteopedia claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In biology, 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 Proteopedia 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 Proteopedia 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 Proteopedia

In research: Proteopedia appears in biology 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 Proteopedia 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: Proteopedia is common in secondary-school and first-year university syllabi. It links to neighbouring topics Creative Commons-licensed databases, Encyclopedias of science, Internet properties established in 2007, so understanding it makes those chapters shorter.
In everyday life: Look for Proteopedia 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 Proteopedia in simple terms?

Proteopedia is a wiki, 3D encyclopedia of proteins and other molecules. Website The site contains a page for all of the entries in the Protein Data Bank (PDB), as well as pages that are more descriptive of protein structures in general such as acetylcholinesterase, hemoglobin, and the photosystem I…

Why does Proteopedia matter?

Because it connects several biology 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 Proteopedia?

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.
