Family: Thiamin biosynthesis kinases

Lineage:

  1. Root: scop
  2. Class: Alpha and beta proteins (a/b) [51349]
    Mainly parallel beta sheets (beta-alpha-beta units)
  3. Fold: Ribokinase-like [53612]
    core: 3 layers: a/b/a; mixed beta-sheet of 8 strands, order 21345678, strand 7 is antiparallel to the rest
    potential superfamily: members of this fold have similar functions but different ATP-binding sites
  4. Superfamily: Ribokinase-like [53613]
    has extra strand located between strands 2 and 3
