Lineage for Species: Pyrococcus furiosus [TaxId: 2261]

1. Root: SCOPe 2.01

2. Class a: All alpha proteins [46456] (284 folds)

3. Fold a.149: RNase III domain-like [69064] (1 superfamily) core: 5 helices; one helix is surrounded by the others

4. Superfamily a.149.1: RNase III domain-like [69065] (2 families)

5. Family a.149.1.2: PF0609-like [140675] (2 proteins) specific to Thermococci; shares conserved carboxylic residues and similar dimerisation mode with the RNase III domain; contains integrated in the fold extra C-terminal helix, making it similar to the core fold of Ribosomal protein S7 (47972)

6. Protein automated matches [190862] (1 species) not a true protein
