SCOPe 2.08: Domain d4q1sx_: 4q1s X:

Lineage for d4q1sx_ (4q1s X:)

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 beta subunit (catalytic) [56252] (7 species)

7. Species Baker's yeast (Saccharomyces cerevisiae) [TaxId:4932] [56254] (202 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 d4q1sx_: 4q1s X: [258280]
   Other proteins in same PDB: d4q1sc1, d4q1sc2, d4q1sd_, d4q1se_, d4q1sf_, d4q1sg_, d4q1sh_, d4q1sm_, d4q1sp_, d4q1sq1, d4q1sq2, d4q1sr_, d4q1ss_, d4q1st_, d4q1su_, d4q1sv_
   automated match to d1rypk_
   complexed with 2yd
