Family: 6-pyruvoyl tetrahydropterin synthase

Lineage:

  1. Root: scop
  2. Class: Alpha and beta proteins (a+b) [53931]
    Mainly antiparallel beta sheets (segregated alpha and beta regions)
  3. Fold: T-fold [55619]
    beta(2)-alpha(2)-beta(2); 2 layers: alpha/beta; antiparallel sheet 1234
    tunnel-shaped: its known members form wide oligomeric barrels different sizes
  4. Superfamily: Tetrahydrobiopterin biosynthesis enzymes-like [55620]
    bind purine or pterin in topologically similar sites between subunits
