SCOP 1.65: Domain d1qcrb1: 1qcr B:17-235

Lineage for d1qcrb1 (1qcr B:17-235)

1. Root: SCOP 1.65

2. Class d: Alpha and beta proteins (a+b) [53931] (234 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] (4 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] (5 PDB entries)

8. Domain d1qcrb1: 1qcr B:17-235 [59027]
   Other proteins in same PDB: d1qcra1, d1qcra2, d1qcrc2, d1qcrc3, d1qcrd2, d1qcrd3, d1qcre1, d1qcre2, d1qcrf_, d1qcrg_, d1qcrh_, d1qcrj_, d1qcrk_
