Structural Classification of Proteins

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] (7)
    N-terminal residue provides two catalytic groups, nucleophile and proton donor

    1. Class II glutamine amidotransferases [56236] (9) picpic
      has slightly different topology than other families do
    2. Penicillin acylase, catalytic domain [56244] (4) picpic
    3. Penicillin V acylase [56248] (1) picpic
    4. Proteasome subunits [56251] (14) picpic
    5. (Glycosyl)asparaginase [56261] (3) picpic
    6. Gamma-glutamyltranspeptidase-like [143906] (4) picpic
      Pfam 01019
    7. SPO2555-like [160846] (1) picpic
      Pfam 06267; DUF1028
  2. Archaeal IMP cyclohydrolase PurO [75569] (1)
    has a putative active site in the same topological location as the Ntn hydrolase but lacks the N-terminal nucleophile

    1. Archaeal IMP cyclohydrolase PurO [75570] (1) picpic
      Pfam 07826
