SCOPe 2.03: Domain d1sqxa1: 1sqx A:1-233

Lineage for d1sqxa1 (1sqx A:1-233)

1. Root: SCOPe 2.03

2. Class d: Alpha and beta proteins (a+b) [53931] (376 folds)

3. Fold d.185: LuxS/MPP-like metallohydrolase [63410] (1 superfamily)
   core: beta-alpha-beta(2)-alpha(2); 2 layers: alpha/beta

4. Superfamily d.185.1: LuxS/MPP-like metallohydrolase [63411] (3 families)
   Share the same "active site motif" HxxEH located in the first core helix, but differ in one of the zinc-binding residues

5. Family d.185.1.1: MPP-like [63412] (6 proteins)
   Common fold elaborated with many additional structures; duplication: each family member consists of two similar domains of beta(2)-alpha(2)-beta(2)-alpha(5)-beta structure, but only the N-terminal domain of MPP beta chain binds the catalytic metal

6. Protein Cytochrome bc1 core subunit 1 [63408] (3 species)

7. Species Cow (Bos taurus) [TaxId:9913] [55997] (18 PDB entries)
   Uniprot P31800

8. Domain d1sqxa1: 1sqx A:1-233 [119035]
   Other proteins in same PDB: d1sqxb1, d1sqxb2, d1sqxc1, d1sqxc2, d1sqxd1, d1sqxd2, d1sqxe1, d1sqxe2, d1sqxf_, d1sqxg_, d1sqxh_, d1sqxi_, d1sqxj_, d1sqxk_
   automated match to d1ntma1
   complexed with fes, hem, sma, uq2
