Lineage for Species: Helicobacter pylori [TaxId: 210]

1. Root: SCOPe 2.02

2. Class c: Alpha and beta proteins (a/b) [51349] (147 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] (25 families) division into families based on beta-sheet topologies

5. Family c.37.1.20: Extended AAA-ATPase domain [81269] (29 proteins) fold is similar to that of RecA, but lacks the last two strands, followed by a family-specific Arg-finger domain

6. Protein ClpX [102391] (1 species) ATPase subunit of ATP-dependent protease
