Lineage for d1tkbb1 (1tkb B:3-337)

  1. Root: SCOPe 2.07
  2. 2434694Class c: Alpha and beta proteins (a/b) [51349] (148 folds)
  3. 2472772Fold 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. 2472773Superfamily c.36.1: Thiamin diphosphate-binding fold (THDP-binding) [52518] (9 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. 2473216Family 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. 2473235Protein Transketolase (TK), PP module [88761] (4 species)
  7. 2473236Species Baker's yeast (Saccharomyces cerevisiae) [TaxId:4932] [88762] (7 PDB entries)
  8. 2473242Domain d1tkbb1: 1tkb B:3-337 [31809]
    Other proteins in same PDB: d1tkba2, d1tkba3, d1tkbb2, d1tkbb3
    complexed with ca, n1t
