SCOP 1.69: Superfamily c.23.16: Class I glutamine amidotransferase-like

Lineage for Superfamily c.23.16: Class I glutamine amidotransferase-like

1. Root: SCOP 1.69

2. Class c: Alpha and beta proteins (a/b) [51349] (136 folds)

3. Fold c.23: Flavodoxin-like [52171] (15 superfamilies)
   3 layers, a/b/a; parallel beta-sheet of 5 strand, order 21345

4. Superfamily c.23.16: Class I glutamine amidotransferase-like [52317] (6 families)
   conserved positions of the oxyanion hole and catalytic nucleophile; different constituent families contain different additional structures

Families:

1. c.23.16.1: Class I glutamine amidotransferases (GAT) [52318] (9 proteins)
   contains a catalytic Cys-His-Glu triad

2. c.23.16.2: DJ-1/PfpI [52325] (6 proteins)
   contains a catalytic triad or dyad different from the class I GAT triad

3. c.23.16.3: Catalase, C-terminal domain [52328] (1 protein)

4. c.23.16.4: Aspartyl dipeptidase PepE [52331] (1 protein)
   probable circular permutation in the common core; contains a catalytic Ser-His-Glu triad

5. c.23.16.5: A4 beta-galactosidase middle domain [82351] (1 protein)
   probable non-catalytic branch of the class I GAT family; overall fold is very similar but the active site is not conserved

6. c.23.16.6: ThuA-like (Pfam 06283) [110486] (1 protein)
   overall fold is very similar the class I GAT family but the putative active site has a different structure
