Brief description of the database:

Zinc fingers are small protein domains in which zinc plays a structural role contributing to the stability of the domain. Zinc fingers are structurally diverse and are present among proteins that perform a broad range of functions in various cellular processes. Zinc fingers typically function as interaction modules and bind to a wide variety of compounds, such as nucleic acids, proteins and small molecules.

We have made a comprehensive classification of zinc finger spatial structures. The zinc finger database has been constructed by manual examination of zinc finger domain structures. We find that each available zinc finger structure can be placed into one of eight fold groups that we define based on the structural properties in the vicinity of the zinc-binding site. Evolutionary relatedness of proteins within fold groups is not implied, but each group is divided into families of potential homologues.
