Superfamily: Tetrahydrobiopterin biosynthesis enzymes-like

bind purine or pterin in topologically similar sites between subunits
link to SUPERFAMILY database - Superfamily

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
    link to SUPERFAMILY database - Superfamily

Families:

  1. GTP cyclohydrolase I [55621] (4) picpic
  2. 6-pyruvoyl tetrahydropterin synthase [55625] (4) picpic
  3. DHN aldolase/epimerase [55628] (4) picpic
    beta-sheets of four subunits form a barrel, closed: n=16, S=16
  4. Urate oxidase (uricase) [55633] (3) picpic
