Lineage for Family c.31.1.4: Transhydrogenase domain III (dIII)

1. Root: SCOP 1.73

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

3. Fold c.31: DHS-like NAD/FAD-binding domain [52466] (1 superfamily) 3 layers: a/b/a; parallel beta-sheet of 6 strands, order 321456; Rossmann-like

4. Superfamily c.31.1: DHS-like NAD/FAD-binding domain [52467] (6 families) binds cofactor molecules in the opposite direction than classical Rossmann fold

5. Family c.31.1.4: Transhydrogenase domain III (dIII) [52484] (1 protein) binds NADP, shares with the pyruvate oxidase FAD-binding domain a common ADP-binding mode
