SCOPe 2.06: Domain d3cxhb2: 3cxh B:219-368

Lineage for d3cxhb2 (3cxh B:219-368)

1. Root: SCOPe 2.06

2. Class d: Alpha and beta proteins (a+b) [53931] (385 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] (7 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 Baker's yeast (Saccharomyces cerevisiae) [TaxId:4932] [64305] (7 PDB entries)

8. Domain d3cxhb2: 3cxh B:219-368 [157112]
