Family: Intron-encoded homing endonucleases

Lineage:

  1. Root: scop
  2. Class: Alpha and beta proteins (a+b) [53931]
    Mainly antiparallel beta sheets (segregated alpha and beta regions)
  3. Fold: His-Me finger endonucleases [54059]
    core: (alpha)-beta-omega_loop-beta-alpha; embeded in larger different structures
  4. Superfamily: His-Me finger endonucleases [54060]
    common motif contains conserved histidine residue and metal-binding site
