SCOPe 2.08: Domain d1ni4d1: 1ni4 D:1-191

Lineage for d1ni4d1 (1ni4 D:1-191)

1. Root: SCOPe 2.08

2. Class c: Alpha and beta proteins (a/b) [51349] (148 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.36.1.7: Branched-chain alpha-keto acid dehydrogenase Pyr module [88741] (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
   automatically mapped to Pfam PF02779

6. Protein E1-beta subunit of pyruvate dehydrogenase, Pyr module [69472] (2 species)

7. Species Human (Homo sapiens) [TaxId:9606] [89653] (4 PDB entries)

8. Domain d1ni4d1: 1ni4 D:1-191 [85732]
   Other proteins in same PDB: d1ni4a1, d1ni4a2, d1ni4b2, d1ni4b3, d1ni4c1, d1ni4c2, d1ni4d2, d1ni4d3
   complexed with k, mg, tpp
