Family: Tryptophan biosynthesis enzymes

Lineage:

  1. Root: scop
  2. Class: Alpha and beta proteins (a/b) [51349]
    Mainly parallel beta sheets (beta-alpha-beta units)
  3. Fold: TIM beta/alpha-barrel [51350]
    contains parallel beta-sheet barrel, closed; n=8, S=8; strand order 12345678
    the first seven superfamilies have similar phosphate-binding sites
  4. Superfamily: Ribulose-phoshate binding barrel [51366]
