SCOPe 2.07: Domain d1trka1: 1trk A:3-337

Lineage for d1trka1 (1trk A:3-337)

1. Root: SCOPe 2.07

2. Class c: Alpha and beta proteins (a/b) [51349] (148 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] (9 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] (3 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 Baker's yeast (Saccharomyces cerevisiae) [TaxId:4932] [88762] (7 PDB entries)

8. Domain d1trka1: 1trk A:3-337 [31803]
   Other proteins in same PDB: d1trka2, d1trka3, d1trkb2, d1trkb3
   complexed with ca, tpp
