Lineage for Family d.113.1.4: NADH pyrophosphatase

1. Root: SCOP 1.71

2. Class d: Alpha and beta proteins (a+b) [53931] (286 folds)

3. Fold d.113: Nudix [55810] (1 superfamily) beta(2)-alpha-beta(3)-alpha; 3 layers: alpha/beta/alpha; mixed sheet contains beta-grasp motif

4. Superfamily d.113.1: Nudix [55811] (5 families)

5. Family d.113.1.4: NADH pyrophosphatase [103214] (1 protein) duplication: consists of two structurally similar domains separated by a rubredoxin-like zinc finger; the N-terminal domain has a rudiment Nudix fold, the C-terminal, probably catalytic, domain has the canonical fold
