POLYVIEW-3D Tutorial

Part 1. Source of structural data

We start by reviewing the set of options that allows one to specify a PDB formatted file with the macromolecule of interest (e.g., protein or DNA/RNA) to be used as input for rendering.

Data source

Both the Protein Data Bank (PDB) deposited entries and the PDB formatted custom files can be submitted to the POLYVIEW server. Lines with ATOM cards are the only required data to be present in the file. For registered PDB entries, it is sufficient to enter a 4-letter code (e.g., 1a4y). In the case when both PDB code and custom PDB file name are specified simultaneously, the server will use the first rather than the latter.

For registered PDB entries, one can choose between the asymmetric unit and the biological unit if the latter is available from the Protein Quaternary Structure (PQS) server. In addition, one can indicate if ligands and/or water molecules defined in the file should be included in the image. The user can also specify the initial orientation of a macromolecule and its relative position by centering specific structural element, such as chain or residue(s) of interest.
