Protein: Class II ketol-acid reductoisomerase (KARI) from Spinach (Spinacia oleracea) [TaxId: 3562]

Lineage:

  1. Root: scop
  2. Class: Alpha and beta proteins (a/b) [51349]
    Mainly parallel beta sheets (beta-alpha-beta units)
  3. Fold: NAD(P)-binding Rossmann-fold domains [51734]
    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. Superfamily: NAD(P)-binding Rossmann-fold domains [51735]
    link to SUPERFAMILY database - Superfamily
  5. Family: 6-phosphogluconate dehydrogenase-like, N-terminal domain [51868]
    the beta-sheet is extended to 8 strands, order 32145678; strands 7 & 8 are antiparallel to the rest
    C-terminal domains also show some similarity
  6. Protein: Class II ketol-acid reductoisomerase (KARI) [51869]
    contains additional subdomain at the N-terminus, partly ordered
  7. Species: Spinach (Spinacia oleracea) [TaxId: 3562] [51870]
