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: Branched-chain alpha-keto acid dehydrogenase Pyr module [88741]
parent family to TK and PFOR heterodimeric protein related to TK; alpha-subunit is the PP module and the N-terminal domain of beta-subunit is the Pyr module
Protein: 2-oxoisovalerate dehydrogenase (E1B), Pyr module [88744]
chain A is alpha-subunit and chain B is beta-subunit
