Protein: N5-carboxyaminoimidazole ribonucleotide synthetase PurK (AIRC), N-domain from Escherichia coli [TaxId: 562]

Lineage:

  1. Root: scop
  2. Class: Alpha and beta proteins (a/b) [51349]
    Mainly parallel beta sheets (beta-alpha-beta units)
  3. Fold: PreATP-grasp domain [52439]
    3 layers: a/b/a; parallel or mixed beta-sheet of 4 to 6 strands
    possible rudiment form of Rossmann-fold domain
  4. Superfamily: PreATP-grasp domain [52440]
    precedes the ATP-grasp domain common to all superfamily members, can contain a substrate-binding function
