Protein: Transketolase (TK), PP module from Leishmania mexicana mexicana [TaxId: 44270]



  1. Root: scop
  2. Class: Alpha and beta proteins (a/b) [51349]
    Mainly parallel beta sheets (beta-alpha-beta units)
  3. Fold: Thiamin diphosphate-binding fold (THDP-binding) [52517]
    3 layers: a/b/a; parallel beta-sheet of 6 strands, order 213465
  4. Superfamily: Thiamin diphosphate-binding fold (THDP-binding) [52518]
    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: TK-like PP module [88760]
    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]
