Protein: GTP cyclohydrolase I 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: 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
   uperfamily
5. Family: GTP cyclohydrolase I [55621]
6. Protein: GTP cyclohydrolase I [55622]
   beta-sheets of five subunits form a barrel, closed: n=20, S=20
7. Species: Escherichia coli [TaxId: 562] [55623]
