SCOPe 2.02: Domain d2r5na2: 2r5n A:2-332

Lineage for d2r5na2 (2r5n A:2-332)

1. Root: SCOPe 2.02

2. Class c: Alpha and beta proteins (a/b) [51349] (147 folds)

3. Fold c.36: Thiamin diphosphate-binding fold (THDP-binding) [52517] (1 superfamily)
   3 layers: a/b/a; parallel beta-sheet of 6 strands, order 213465

4. Superfamily c.36.1: Thiamin diphosphate-binding fold (THDP-binding) [52518] (8 families)
   there are two different functional modules of this fold: pyridine-binding (Pyr) and pyrophosphate-binding (PP) modules
   two Pyr and two PP modules assemble together in a conserved heterotetrameric core that binds two THDP coenzyme molecules

5. Family c.36.1.10: TK-like PP module [88760] (2 proteins)
   different order of the modules, PP module is N-terminal, Pyr module is next to it followed by a Rossmann-like domain

6. Protein Transketolase (TK), PP module [88761] (4 species)

7. Species Escherichia coli [TaxId:562] [89656] (4 PDB entries)

8. Domain d2r5na2: 2r5n A:2-332 [151592]
   Other proteins in same PDB: d2r5na1, d2r5na3, d2r5nb1, d2r5nb3
   automatically matched to d1qgda2
   complexed with ca, edo, r5p, rp5, tpp
