SCOP 1.73: Domain d1qhla_: 1qhl A:

Lineage for d1qhla_ (1qhl A:)

1. Root: SCOP 1.73

2. Class c: Alpha and beta proteins (a/b) [51349] (141 folds)

3. Fold c.37: P-loop containing nucleoside triphosphate hydrolases [52539] (1 superfamily)
   3 layers: a/b/a, parallel or mixed beta-sheets of variable sizes

4. Superfamily c.37.1: P-loop containing nucleoside triphosphate hydrolases [52540] (24 families)
   division into families based on beta-sheet topologies

5. Family c.37.1.12: ABC transporter ATPase domain-like [52686] (20 proteins)
   there are two additional subdomains inserted into the central core that has a RecA-like topology

6. Protein Cell division protein MukB [52695] (1 species)

7. Species Escherichia coli [TaxId:562] [52696] (1 PDB entry)

8. Domain d1qhla_: 1qhl A: [32382]
   N-terminal (sub)domain only; in the absence of the C-terminal domain complementing the central core structure, the P-loop region folds in a helix-loop-helix structure
