Protein: E1-beta subunit of pyruvate dehydrogenase, Pyr module from Archaeon Pyrobaculum aerophilum [TaxId: 13773]

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: 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
  6. Protein: E1-beta subunit of pyruvate dehydrogenase, Pyr module [69472]
  7. Species: Archaeon Pyrobaculum aerophilum [TaxId: 13773] [69473]
