DALI Domain dictionary

Dietmann, S., et al., A fully automatic evolutionary classification of protein folds Dali Domain Dictionary version 3. Nucleic Acids Res, 2001. 29(1) p. 55-7. 

All current structural classification methods are based on the same scheme Protein structures are first divided into discrete, globular domains, which are then classified at the levels of (1) class, (2) folds, (3) superfa-milies, and (4) families. The differences among existing schemes come from the methods that define the domains and the procedures that classify. After reviewing the terms that define a classification, the three main protein structure classifications available, SCOP, CATH, and the DALI Domain Dictionary (DDD), will be described. Links to these databases and related services are listed in Table 7.
