SCOP 1.69: Domain d1be3b1: 1be3 B:21-235

Lineage for d1be3b1 (1be3 B:21-235)

1. Root: SCOP 1.69

2. Class d: Alpha and beta proteins (a+b) [53931] (279 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] (12 PDB entries)

8. Domain d1be3b1: 1be3 B:21-235 [58952]
   Other proteins in same PDB: d1be3a1, d1be3a2, d1be3c2, d1be3c3, d1be3d2, d1be3d3, d1be3e1, d1be3e2, d1be3f_, d1be3g_, d1be3h_, d1be3j_, d1be3k_
