Lineage for d1a4ia1 (1a4i A:127-296)

  1. Root: SCOPe 2.08
  2. 2826024Class c: Alpha and beta proteins (a/b) [51349] (148 folds)
  3. 2841004Fold c.2: NAD(P)-binding Rossmann-fold domains [51734] (1 superfamily)
    core: 3 layers, a/b/a; parallel beta-sheet of 6 strands, order 321456
    The nucleotide-binding modes of this and the next two folds/superfamilies are similar
  4. 2841005Superfamily c.2.1: NAD(P)-binding Rossmann-fold domains [51735] (13 families) (S)
  5. 2845190Family c.2.1.7: Aminoacid dehydrogenase-like, C-terminal domain [51883] (12 proteins)
    extra N-terminal helix displaces the C-terminal helix (following strand 6) from its usual position creating a family nicotineamide-binding site
  6. 2845323Protein Methylenetetrahydrofolate dehydrogenase/cyclohydrolase [51894] (3 species)
    the two-domain organization is similar to that of aminoacid dehydrogenases, but both domains are truncated
  7. 2845329Species Human (Homo sapiens) [TaxId:9606] [51895] (7 PDB entries)
  8. 2845330Domain d1a4ia1: 1a4i A:127-296 [30278]
    Other proteins in same PDB: d1a4ia2, d1a4ib2
    complexed with ndp
    missing some secondary structures that made up less than one-third of the common domain
