Lineage for Fold b.68: 6-bladed beta-propeller
- Root: SCOP 1.73
Class b: All beta proteins [48724] (165 folds) 
Fold b.68: 6-bladed beta-propeller [50938] (11 superfamilies)
consists of six 4-stranded beta-sheet motifs; meander
Superfamilies:
b.68.1: Sialidases [50939] (2 families) 
b.68.2: Soluble quinoprotein glucose dehydrogenase [50952] (1 family) 
b.68.3: Thermostable phytase (3-phytase) [50956] (1 family) 
b.68.4: TolB, C-terminal domain [50960] (1 family) 
b.68.5: YWTD domain [63825] (1 family) b.68.6: Calcium-dependent phosphotriesterase [63829] (2 families) 
b.68.7: Tricorn protease N-terminal domain [69304] (1 family)
possibly related to the second domain of tricorn protease (a distorted 7-bladed beta-propeller)
b.68.8: Fucose-specific lectin [89372] (1 family) 
b.68.9: NHL repeat [101898] (1 family) 
b.68.10: GyrA/ParC C-terminal domain-like [101904] (1 family)
beta-pinwheel, a variant of beta-propeller fold; unlike an canonical beta-propeller, strands 1 and 4 of each four-strand repeat unit are in one blade whereas strands 2 and 3 are in the next blade
b.68.11: Kelch motif [117281] (1 family)
