Lineage for Species: Azotobacter vinelandii

1. Root: SCOP 1.69

2. Class c: Alpha and beta proteins (a/b) [51349] (136 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] (5 families) the constituent families form similar dimers

5. Family c.77.1.2: Monomeric isocitrate dehydrogenase [82526] (1 protein) the active site is contained within one subunit between the canonical ICDH fold and a large insert domain that itself is a probable rudiment form of ICDH fold resulted from duplication, domain swapping and deletion

6. Protein Monomeric isocitrate dehydrogenase [82527] (1 species)

7. Species Azotobacter vinelandii [TaxId:354] [82528] (1 PDB entry) the insert region spans residues 150-404
