Lineage for Species: Thermus thermophilus [TaxId: 274]

1. Root: SCOPe 2.07

2. Class c: Alpha and beta proteins (a/b) [51349] (148 folds)

3. Fold c.8: The "swivelling" beta/beta/alpha domain [52008] (10 superfamilies) 3 layers: b/b/a; the central sheet is parallel, and the other one is antiparallel; there are some variations in topology this domain is thought to be mobile in most multi-domain proteins known to contain it

4. Superfamily c.8.7: RraA-like [89562] (2 families) structural similarity and possible distant homology to the phosphohistidine domain of pyruvate phosphate dikinase

5. Family c.8.7.1: RraA-like [89563] (5 proteins) aka MenG-like; characterized as regulator of RNase E activity A (RraA) that globally modulates RNA abundance in E. coli automatically mapped to Pfam PF03737

6. Protein Demethylmenaquinone methyltransferase [102196] (1 species) as (mis)annotated in the PDB entry; RraA homologue

7. Species Thermus thermophilus [TaxId:274] [102197] (1 PDB entry)
