Lineage for d1tkaa2 (1tka A:338-534)

  1. Root: SCOP 1.67
  2. 383641Class c: Alpha and beta proteins (a/b) [51349] (130 folds)
  3. 393047Fold 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. 393048Superfamily c.36.1: Thiamin diphosphate-binding fold (THDP-binding) [52518] (8 families) (S)
    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. 393127Family c.36.1.6: TK-like Pyr module [88735] (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. 393134Protein Transketolase (TK), Pyr module [88736] (3 species)
  7. 393135Species Baker's yeast (Saccharomyces cerevisiae) [TaxId:4932] [88737] (7 PDB entries)
  8. 393144Domain d1tkaa2: 1tka A:338-534 [31816]
    Other proteins in same PDB: d1tkaa1, d1tkaa3, d1tkab1, d1tkab3
