SCOPe 2.08: Domain d2fakb_: 2fak B:

Lineage for d2fakb_ (2fak B:)

1. Root: SCOPe 2.08

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

3. Fold d.153: Ntn hydrolase-like [56234] (2 superfamilies)
   4 layers: alpha/beta/beta/alpha; has an unusual sheet-to-sheet packing

4. Superfamily d.153.1: N-terminal nucleophile aminohydrolases (Ntn hydrolases) [56235] (8 families)
   N-terminal residue provides two catalytic groups, nucleophile and proton donor

5. Family d.153.1.4: Proteasome subunits [56251] (4 proteins)

6. Protein Proteasome alpha subunit (non-catalytic) [56255] (10 species)
   contains an extension to the common fold at the N-terminus

7. Species Baker's yeast (Saccharomyces cerevisiae) [TaxId:4932] [56257] (240 PDB entries)
   The structure of yeast proteasome complexed with the proteasome activator pa26 is available from PDB (1fnt). The 1FNT entry designates protein chains by both upper case and lower case letters creating problems with its processing and presentation in SCOP; the proteasome activator pa26 structure is classified elsewhere in SCOP (a.24.8)

8. Domain d2fakb_: 2fak B: [133198]
   Other proteins in same PDB: d2fak1_, d2fak2_, d2fakd_, d2fakg_, d2fakh_, d2faki_, d2fakj_, d2fakk_, d2fakl_, d2fakm_, d2fakn_, d2fakr_, d2faku_, d2fakv_, d2fakw_, d2fakx_, d2faky_, d2fakz_
   automated match to d1g65b_
   complexed with sa1
