Lineage for Species: Bacillus subtilis [TaxId: 1423]

1. Root: SCOPe 2.08

2. Class a: All alpha proteins [46456] (290 folds)

3. Fold a.4: DNA/RNA-binding 3-helical bundle [46688] (14 superfamilies) core: 3-helices; bundle, closed or partly opened, right-handed twist; up-and down

4. Superfamily a.4.5: 'Winged helix' DNA-binding domain [46785] (86 families) contains a small beta-sheet (wing)

5. Family a.4.5.69: HxlR-like [140304] (6 proteins) Pfam PF01638; DUF24; the N- and C-terminal helical extensions to the common fold form the dimer interface similar to that of the ArsR-like family (46801)
