In  SWISS-PROT, as in most other sequence databases, two classes  of  data
can be distinguished: the core data and the annotation.

For each sequence entry the core data consists of:

   o The sequence data;
   o The citation information (bibliographical references);
   o The taxonomic data (description of the biological source of the
     protein).

The annotation consists of the description of the following items:

   o Function(s) of the protein;
   o Post-translational modification(s). For example carbohydrates,
     phosphorylation, acetylation, GPI-anchor, etc.;
   o Domains and sites. For example calcium binding regions, ATP-binding
     sites, zinc fingers, homeoboxes, SH2 and SH3 domains, kringle, etc.;
   o Secondary structure. For example alpha helix, beta sheet, etc.;
   o Quaternary structure. For example homodimer, heterotrimer, etc.;
   o Similarities to other proteins;
   o Disease(s) associated with deficiencie(s) in the protein;
   o Sequence conflicts, variants, etc.
