SCOP 1.73: Domain d1sqxa2: 1sqx A:234-446

Lineage for d1sqxa2 (1sqx A:234-446)

1. Root: SCOP 1.73

2. Class d: Alpha and beta proteins (a+b) [53931] (334 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] (2 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)

8. Domain d1sqxa2: 1sqx A:234-446 [119036]
   Other proteins in same PDB: d1sqxb1, d1sqxb2, d1sqxc1, d1sqxc2, d1sqxd1, d1sqxd2, d1sqxf1, d1sqxg1, d1sqxh1, d1sqxi1, d1sqxj1
   automatically matched to d1be3a2
   complexed with fes, hem, sma, uq2
