Fold: TBP-like

beta-alpha-beta(4)-alpha

Lineage:

1. Root: scop
2. Class: Alpha and beta proteins (a+b)
   Mainly antiparallel beta sheets (segregated alpha and beta regions)
3. Fold: TBP-like
   beta-alpha-beta(4)-alpha

Superfamilies:

1. TATA-box binding protein-like (2)
2. Phosphoglucomutase, C-terminal domain (1)
   contains a single copy of this fold and an extra beta-strand at the C-terminus
3. Bet v1-like (3)
   contains a single copy of this fold with a alpha-beta2 insertion after the first helix; there is a cavity between the beta-sheet and the long C-terminal helix
