SCOPe 2.03: Domain d2bfea1: 2bfe A:6-400

Lineage for d2bfea1 (2bfe A:6-400)

1. Root: SCOPe 2.03

2. Class c: Alpha and beta proteins (a/b) [51349] (147 folds)

3. Fold 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. Superfamily c.36.1: Thiamin diphosphate-binding fold (THDP-binding) [52518] (9 families)
   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 c.36.1.11: Branched-chain alpha-keto acid dehydrogenase PP module [88766] (5 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

6. Protein Branched-chain alpha-keto acid dehydrogenase, PP module [88767] (2 species)

7. Species Human (Homo sapiens) [TaxId:9606] [88768] (19 PDB entries)
   Uniprot P12694 52-445

8. Domain d2bfea1: 2bfe A:6-400 [146140]
   Other proteins in same PDB: d2bfeb1, d2bfeb2
   complexed with cl, gol, k, mn, mrd, tdp
