Fold: Ntn hydrolase-like

4 layers: alpha/beta/beta/alpha; has an unusual sheet-to-sheet packing

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

Superfamilies:

  1. N-terminal nucleophile aminohydrolases (Ntn hydrolases) [56235] (6) picpic
    N-terminal residue provides two catalytic groups, nucleophile and proton donor
  2. Archaeal IMP cyclohydrolase PurO [75569] (1) picpic
    has a putative active site in the same topological location as the Ntn hydrolase but lacks the N-terminal nucleophile
