SCOPe 2.02: Domain d1sqvb1: 1sqv B:18-235

Lineage for d1sqvb1 (1sqv B:18-235)

1. Root: SCOPe 2.02

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] (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 2 [63409] (3 species)

7. Species Cow (Bos taurus) [TaxId:9913] [56000] (18 PDB entries)
   Uniprot P23004

8. Domain d1sqvb1: 1sqv B:18-235 [119022]
   Other proteins in same PDB: d1sqva1, d1sqva2, d1sqvc1, d1sqvc2, d1sqvd1, d1sqvd2, d1sqvf_, d1sqvg_, d1sqvh_, d1sqvi1, d1sqvj_, d1sqvk_
   automatically matched to d1bccb1
   complexed with fes, hem, uhd, uq2
