VIPERdb is a database for
icosahedral
virus
capsid structures
.
The emphasis of the resource is on providing data from structural
and computational analyses on these systems, as well as high quality
renderings for visual exploration. In addition, all virus capsids
are placed in a single icosahedral orientation convention,
facilitating comparison
between different structures. The web site includes powerful
search utilities
,
links to other relevant databases, background information
on virus capsid structure, and useful
database interface tools.

You have different options on how to start using VIPERdb. You can jump
to any section in the site using the
Top Menu. If you are looking for a specific
entry, you can look for it on the X-Ray
or Cryo-EM drop-down lists
on the top, or type its PDB-ID
in the correspondig field above.
If you are not sure, you can access the Search Page
here and look for it by Name.
All virus entries are grouped into
Families
,
you can see a list
here with links to all their members.

All database information
(from echo $numEntries ?> viruses)
is accessed through the
Info Page, which
shows all pertinent data using different database interfaces
(Biodata, 3D Structure, 2D Φ-Ψ Maps)
for each individually selected entry.
If you are new to VIPERdb, you can get familiar with the site by accessing the Info Page for some of the most popular spherical viruses. Here is just a small sample (click images to open corresponding Info Page):
