F: Unmapped domains

Pseudo group of domains that do not map to PFam family profiles. Domains inside should not be considered as in one family.

X: Rubredoxin-like

binds one zinc with two CxxC motifs on two beta-hairpins

X: RING/U-box-like

binds two zincs. one in the same way as rubredoxin, probably related to rubredoxin. the other in a similar way as glucocorticoid receptor

X: Glucocorticoid receptor-like

binds zinc with one beta-hairpin and one helix, the helix binds DNA

extended segmentsextended, non-globular segments, frequently bind to other proteins to form complexes
