SCOP 1.73: Domain d1tdfa2: 1tdf A:119-244

Lineage for d1tdfa2 (1tdf A:119-244)

1. Root: SCOP 1.73

2. Class c: Alpha and beta proteins (a/b) [51349] (141 folds)

3. Fold c.3: FAD/NAD(P)-binding domain [51904] (1 superfamily)
   core: 3 layers, b/b/a; central parallel beta-sheet of 5 strands, order 32145; top antiparallel beta-sheet of 3 strands, meander

4. Superfamily c.3.1: FAD/NAD(P)-binding domain [51905] (7 families)

5. Family c.3.1.5: FAD/NAD-linked reductases, N-terminal and central domains [51943] (15 proteins)
   duplication: both domains have similar folds and functions
   most members of the family contain common C-terminal alpha+beta domain
