Lineage for Family c.36.1.3: Branched-chain alpha-keto acid dehydrogenase THDP-binding domains

  1. Root: SCOP 1.63
  2. 235644Class c: Alpha and beta proteins (a/b) [51349] (117 folds)
  3. 242757Fold 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. 242758Superfamily c.36.1: Thiamin diphosphate-binding fold (THDP-binding) [52518] (4 families) (S)
    both pyridine (Pyr)- and pyrophosphate (PP)-binding modules have this fold
    conserved core consists of two Pyr and two PP-modules and binds two coenzyme molecules
  5. 242884Family c.36.1.3: Branched-chain alpha-keto acid dehydrogenase THDP-binding domains [52531] (3 proteins)
    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

Proteins:

  1. 2428852-oxoisovalerate dehydrogenase (E1B), PP and Pyr modules [52534] (1 species)
    chain A is alpha-subunit and chain B is beta-subunit
  2. 242889Branched-chain alpha-keto acid dehydrogenase, PP and Pyr modules [52532] (1 species)
  3. 242893E1-beta subunit of pyruvate dehydrogenase, Pyr module [69472] (1 species)
    structure determined on its own rather in the complex with E1-alpha
