Lineage for Species: Thermococcus onnurineus [TaxId: 342948]

1. Root: SCOPe 2.08

2. Class d: Alpha and beta proteins (a+b) [53931] (396 folds)

3. Fold d.58: Ferredoxin-like [54861] (62 superfamilies) alpha+beta sandwich with antiparallel beta-sheet; (beta-alpha-beta)x2

4. Superfamily d.58.58: CRISPR associated protein Cas2-like [143430] (2 families) contains extra C-terminal beta-strand that integrates into the beta-sheet of the other subunit in the homodimer, a probable biological unit of this superfamily
