The overall flexibility of the selected soluble epoxide hydrolases. A) Mus musculus EH (msEH), B) Homo sapiens EH (hsEH), C) Trichoderma reesei EH (TrEH), D) Solanum tuberosum EH (StEH1), E) Vigna radiata EH (VrEH2), F) Bacillus megaterium EH (bmEH), and thermophilic G) CH65-EH, and H) Sibe-EH from an unknown source organism. The proteins are shown as springs, with the thin white lines indicating lower flexibility, and thicker reddish lines - higher flexibility.
