Lineage for Superfamily c.36.1: Thiamin diphosphate-binding fold (THDP-binding)

  1. Root: SCOPe 2.06
  2. 2078559Class c: Alpha and beta proteins (a/b) [51349] (148 folds)
  3. 2108258Fold c.36: Thiamin diphosphate-binding fold (THDP-binding) [52517] (1 superfamily)
    3 layers: a/b/a; parallel beta-sheet of 6 strands, order 213465
  4. 2108259Superfamily c.36.1: Thiamin diphosphate-binding fold (THDP-binding) [52518] (9 families) (S)
    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

Families:

  1. 2108260c.36.1.5: Pyruvate oxidase and decarboxylase Pyr module [88724] (8 protein domains)
    the N-terminal, Pyr module is separated from the C-terminal, PP module by an alpha/beta domain of Rossmann-like topology
    automatically mapped to Pfam PF02776
  2. 2108389c.36.1.6: TK-like Pyr module [88735] (2 protein domains)
    different order of the modules, PP module is N-terminal, Pyr module is next to it followed by a Rossmann-like domain
  3. 2108430c.36.1.7: Branched-chain alpha-keto acid dehydrogenase Pyr module [88741] (5 protein domains)
    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
    automatically mapped to Pfam PF02779
  4. 2108512c.36.1.8: PFOR Pyr module [88746] (1 protein)
    domains VI, I and II are arranged in the same way as the TK PP, Pyr and C domains
    automatically mapped to Pfam PF01855
  5. 2108535c.36.1.9: Pyruvate oxidase and decarboxylase PP module [88749] (8 protein domains)
    the N-terminal, Pyr module is separated from the C-terminal, PP module by an alpa/beta domain of Rossmann-like topology
  6. 2108664c.36.1.10: TK-like PP module [88760] (3 protein domains)
    different order of the modules, PP module is N-terminal, Pyr module is next to it followed by a Rossmann-like domain
  7. 2108723c.36.1.11: Branched-chain alpha-keto acid dehydrogenase PP module [88766] (5 protein domains)
    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
  8. 2108828c.36.1.12: PFOR PP module [88771] (1 protein)
    domains VI, I and II are arranged in the same way as the TK PP, Pyr and C domains
  9. 2108851c.36.1.0: automated matches [227300] (1 protein)
    not a true family
