dessin p-sea The program P-SEA (Protein Secondary Element Assignment) enables you to retrieve the secondary structure of a known 3D protein structure (and thereby extract the amino acid sequence of the protein) (Labesse, Colloc'h, Pothier & Mornon, 1997, Bioinformatics).  Assignment usually lasts a few seconds.

Enter the Protein Data Bank ID of your protein (four letter code):   

Or Browse for your 3D structure file:   

In this case, you need an ASCII (plain text) file containing a properly formatted 3D protein structure (PDB file format). Unix/Linux compressed files (.gz or .Z) are accepted. Example: 1xva.pdb
