SCOP 1.69: Domain d1tkba1: 1tkb A:3-337

Lineage for d1tkba1 (1tkb A:3-337)

1. Root: SCOP 1.69

2. Class c: Alpha and beta proteins (a/b) [51349] (136 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] (3 species)

7. Species Baker's yeast (Saccharomyces cerevisiae) [TaxId:4932] [88762] (7 PDB entries)

8. Domain d1tkba1: 1tkb A:3-337 [31807]
   Other proteins in same PDB: d1tkba2, d1tkba3, d1tkbb2, d1tkbb3
