Lineage for Species: Pseudomonas aeruginosa [TaxId: 287]

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)

6. Protein Hypothetical protein PA1607 [140307] (1 species) includes extra C-terminal SH3-like subdomain, which is segment-swapped in the dimer

7. Species Pseudomonas aeruginosa [TaxId:287] [140308] (1 PDB entry) Uniprot Q9I3B4 5-146
