SCOP 1.67: Family d.153.1.1: Class II glutamine amidotransferases

Lineage for Family d.153.1.1: Class II glutamine amidotransferases

1. Root: SCOP 1.67

2. Class d: Alpha and beta proteins (a+b) [53931] (260 folds)

3. Fold d.153: Ntn hydrolase-like [56234] (2 superfamilies)
   4 layers: alpha/beta/beta/alpha; has an unusual sheet-to-sheet packing

4. Superfamily d.153.1: N-terminal nucleophile aminohydrolases (Ntn hydrolases) [56235] (5 families)
