| - | SEQRES records give the sequences of the three peptide chains (named A, B and C), which are very short in this example but usually span multiple lines. | + | SEQRES records give the sequences of the three peptide chains (named A, B and C), and usually span multiple lines. |
| - | ATOM records describe the coordinates of the atoms that are part of the protein. For example, the first ATOM line above describes the alpha-N atom of the first residue of peptide chain A, which is a proline residue; the first three floating point numbers are its x, y and z coordinates and are in units of Ångströms.[3] The next three columns are the occupancy, temperature factor, and the element name, respectively. | + | ATOM records describe the coordinates of the atoms that are part of the protein.
