Protein: A4 beta-galactosidase from Thermus thermophilus [TaxId: 274]

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: (Trans)glycosidases [51445]
    link to SUPERFAMILY database - Superfamily
  5. Family: Amylase, catalytic domain [51446]
    members of the family may contain various insert subdomains
    in alpha-amylases and closer relatives this domain is usually followed by a common all-beta domain
  6. Protein: A4 beta-galactosidase [82246]
    the catalytic domain is very similar to that of the bacterial beta-amylase; but contains a typical alpha-amylase extra domain
  7. Species: Thermus thermophilus [TaxId: 274] [82247]
