Lineage for Protein: DNA topoisomerase III

  1. Root: SCOPe 2.08
  2. 3012399Class e: Multi-domain proteins (alpha and beta) [56572] (74 folds)
  3. 3018324Fold e.10: Prokaryotic type I DNA topoisomerase [56711] (1 superfamily)
    4 domains: (1) Toprim alpha/beta; (2&4) "winged helix"-like; (3) barrel: n=6, S=8
  4. 3018325Superfamily e.10.1: Prokaryotic type I DNA topoisomerase [56712] (2 families) (S)
    duplication: the protein chain passing through the domains 2-4 makes two structural repeats
    The active site is formed by the toprim and "winged helix" domains (domains 1 and 4); these two domains are also found in the type II topoisomerase (DNA gyrase A) and in the alpha subunit of topoisomerase IV
  5. 3018326Family e.10.1.1: Prokaryotic type I DNA topoisomerase [56713] (4 proteins)
    domain 4 contains the catalytic tyrosine residue
  6. 3018343Protein DNA topoisomerase III [56716] (1 species)
