Most proteins are globular proteins. This page uses the human spliceosomal protein U5-15kD to illustrate some basic features of globular proteins. Specifically:

You may include any references to papers as in: the use of JSmol in Proteopedia <ref>DOI 10.1002/ijch.201300024</ref> or to the article describing Jmol <ref>PMID:21638687</ref> to the rescue.

1. Globular proteins are compact and rarely have internal cavities.
-
== Disease ==

2. Globular protein structure is primarily stabilized by the hydrophobic interaction.

== Relevance ==

3. Globular proteins have mixed secondary structure.

(U5-15kD is a component of the U5 small nuclear ribosomal protein particle (snRNP). This in turn is a component of the spliceosome, a macromolecular assembly involved in converting primary transcripts into functional mRNAs. U5-15kD was chosen for this page because it is small, but has all of the features necessary to illustrate the points being made.)

This is a sample scene created with SAT to <scene name="/12/3456/Sample/1">color</scene> by Group, and another to make <scene name="/12/3456/Sample/2">a transparent representation</scene> of the protein. You can make your own scenes on SAT starting from scratch or loading and editing one of these sample scenes.

The <scene name='58/587846/1qgv_sf/2'>space filling model</scene> of the protein shows that the protein is compact, globular, and has no signs of internal cavities.

Colouring the <scene name='58/587846/1qgv_sf_pnp/2'>hydrophilic and hydrophobic residues</scene> shows that the interior of the protein is primarily hydrophobic (red) and the exterior is primarily hydrophilic (blue).

The <scene name='58/587846/1qgv_ca/2'>cartoon view</scene> of the protein shows that the protein has mixed secondary structure. There are three segments of alpha-helix (magenta), six segments of beta-pleated sheet (gold), both parallel and anti-parallel, and some irregular regions (white).
