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 uperfamily
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
