Structural Classification of Proteins
home mail help root up expand collapse

Fold: T-fold

beta(2)-alpha(2)-beta(2); 2 layers: alpha/beta; antiparallel sheet 1234
tunnel-shaped: its known members form wide oligomeric barrels different sizes

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

Superfamilies:

  1. Tetrahydrobiopterin biosynthesis enzymes-like [55620] (4) picpic
    bind purine or pterin in topologically similar sites between subunits

  2. ApbE-like [143631] (2) picpic
    duplication: contains two differently decorated beta(2)-alpha(2)-beta(2) subdomains, similar to other T-fold domains; probably does not form the tunnel-shaped oligomers
