Lineage for Family d.3.1.11: Ubiquitin thiolesterase protein OTUB2 (Otubain-2)

1. Root: SCOP 1.71

2. Class d: Alpha and beta proteins (a+b) [53931] (286 folds)

3. Fold d.3: Cysteine proteinases [54000] (1 superfamily) consists of one alpha-helix and 4 strands of antiparallel beta-sheet and contains the catalytic triad Cys-His-Asn

4. Superfamily d.3.1: Cysteine proteinases [54001] (12 families) the constitute families differ by insertion into and circular permutation of the common catalytic core made of one alpha-helix and 3-strands of beta-sheet

5. Family d.3.1.11: Ubiquitin thiolesterase protein OTUB2 (Otubain-2) [110773] (1 protein) probably the same as Pfam 02338, OTU-like cysteine protease, but 1TFF (SQ Q96DC9) was not detected by the Pfam model
