SCOPe Funding Alert: SCOPe support from the NIH ended in April 2016. John-Marc Chandonia is the primary maintainer and has continued to develop SCOPe using vacation time. Three proposals to the NIH for continued funding have been unsuccessful. If our current NIH proposal is not funded, SCOPe will shut down permanently in Summer 2017 as Dr. Chandonia will need to seek a new position.

Lineage for Fold e.10: Prokaryotic type I DNA topoisomerase

  1. Root: SCOPe 2.06
  2. 2217451Class e: Multi-domain proteins (alpha and beta) [56572] (69 folds)
  3. 2221735Fold 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

Superfamily:

  • 2221736e.10.1: Prokaryotic type I DNA topoisomerase [56712] (1 family) (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
