Evolutionary classification of protein domain structures
alpha arraysalpha-helix arrays with mainly perpendicular helices
alpha bundlesalpha-helix bundles with mainly parallel helices
Pseudo group of domains that do not map to PFam family profiles. Domains inside should not be considered as in one family.
