Protein: Asparagine synthetase B, N-terminal domain from Escherichia coli [TaxId: 562]

Lineage:

  1. Root: scop
  2. Class: Alpha and beta proteins (a+b) [53931]
    Mainly antiparallel beta sheets (segregated alpha and beta regions)
  3. Fold: Ntn hydrolase-like [56234]
    4 layers: alpha/beta/beta/alpha; has an unusual sheet-to-sheet packing
  4. Superfamily: N-terminal nucleophile aminohydrolases (Ntn hydrolases) [56235]
    N-terminal residue provides two catalytic groups, nucleophile and proton donor
