Lineage for Family c.36.1.8: PFOR Pyr module

1. Root: SCOP 1.65

2. Class c: Alpha and beta proteins (a/b) [51349] (121 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.36.1.8: 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
