Lineage for Fold b.69: 7-bladed beta-propeller
- Root: SCOPe 2.08
Class b: All beta proteins [48724] (180 folds) 
Fold b.69: 7-bladed beta-propeller [50964] (15 superfamilies)
consists of seven 4-stranded beta-sheet motifs; meander
Superfamilies:
b.69.1: Galactose oxidase, central domain [50965] (2 families) 
b.69.2: YVTN repeat-like/Quinoprotein amine dehydrogenase [50969] (4 families) 
b.69.3: Nitrous oxide reductase, N-terminal domain [50974] (1 family) 
b.69.4: WD40 repeat-like [50978] (4 families)
also contains 8-bladed propellers
b.69.5: RCC1/BLIP-II [50985] (2 families)
two families are clearly related but differ by the number of strands per blade
b.69.6: Clathrin heavy-chain terminal domain [50989] (1 family) 
b.69.7: Peptidase/esterase 'gauge' domain [50993] (3 families) 
b.69.8: Integrin alpha N-terminal domain [69318] (2 families) 
b.69.9: Tricorn protease domain 2 [69322] (1 family)
distorted 7-bladed beta-propeller fold; possibly related to the N-terminal domain of tricorn protease (a 6-bladed beta-propeller)
b.69.10: 3-carboxy-cis,cis-mucoante lactonizing enzyme [75011] (1 family)
automatically mapped to Pfam PF10282
b.69.11: Putative isomerase YbhE [101908] (1 family)
automatically mapped to Pfam PF10282
b.69.12: Sema domain [101912] (1 family)
irregular 7-bladed beta-propeller with a large insertion in the fifth blade
automatically mapped to Pfam PF01403b.69.13: Oligoxyloglucan reducing end-specific cellobiohydrolase [110296] (2 families)
duplication: # two beta-propeller domains are swapped with the N-terminal strands; similar domain arrangment to the Actin interacting protein 1 (89378)
b.69.14: Nucleoporin domain [117289] (1 family) 
b.69.15: Retinal pigment epithelial membrane protein-like [310595] (1 family)
Pfam PF03055
