Lineage for Species: Salmonella typhimurium [TaxId: 90371]

1. Root: SCOPe 2.08

2. Class c: Alpha and beta proteins (a/b) [51349] (148 folds)

3. Fold c.77: Isocitrate/Isopropylmalate dehydrogenase-like [53658] (1 superfamily) consists of two intertwined (sub)domains related by pseudo dyad; duplication 3 layers: a/b/a; single mixed beta-sheet of 10 strands, order 213A945867 (A=10); strands from 5 to 9 are antiparallel to the rest

4. Superfamily c.77.1: Isocitrate/Isopropylmalate dehydrogenase-like [53659] (6 families) the constituent families form similar dimers
