SCOP 1.67: Domain d1pyda3: 1pyd A:361-556

Lineage for d1pyda3 (1pyd A:361-556)

1. Root: SCOP 1.67

2. Class c: Alpha and beta proteins (a/b) [51349] (130 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] (8 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.36.1.9: Pyruvate oxidase and decarboxylase PP module [88749] (7 proteins)
   the N-terminal, Pyr module is separated from the C-terminal, PP module by an alpa/beta domain of Rossmann-like topology

6. Protein Pyruvate decarboxylase [88750] (3 species)

7. Species Brewer's yeast (Saccharomyces), uvarum strain [TaxId:230603] [88751] (1 PDB entry)

8. Domain d1pyda3: 1pyd A:361-556 [31774]
   Other proteins in same PDB: d1pyda1, d1pyda2, d1pydb1, d1pydb2
