Family: TK-like Pyr module

different order of the modules, PP module is N-terminal, Pyr module is next to it followed by a Rossmann-like domain

Lineage:

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 Pyr module [88735]
   different order of the modules, PP module is N-terminal, Pyr module is next to it followed by a Rossmann-like domain
