What Are Protein 3D Structure Data?
by Eric Martz, September 2005
Caveat: "Structure" in bioinformatics can mean sequence structure or 3D structure.
    Atomic Coordinates
    + Chemical and Protein Annotations
    (element, amino acid name, position in amino acid, chain, sequence number):
  1. 4 Amino Acids (65 atoms).
  2. 3D Data as Text.
  3. A Small Protein (56 amino acids, ~1000 atoms).
The above displays were made with ProteinExplorer.Org's MolSlides.Org capability. Protein Explorer is the easiest way to see and understand any macromolecular structure data. Molecular displays are rendered with the Jmol java applet (open source, Jmol.Org).
