SCOPe 2.08: Domain d2afib_: 2afi B:

Lineage for d2afib_ (2afi B:)

1. Root: SCOPe 2.08

2. Class c: Alpha and beta proteins (a/b) [51349] (148 folds)

3. Fold c.92: Chelatase-like [53799] (3 superfamilies)
   duplication: tandem repeat of two domains; 3 layers (a/b/a); parallel beta-sheet of 4 strands, order 2134

4. Superfamily c.92.2: 'Helical backbone' metal receptor [53807] (5 families)
   contains a long alpha helical insertion in the interdomain linker

5. Family c.92.2.3: Nitrogenase iron-molybdenum protein [53816] (3 proteins)
   contains three domains of this fold; "Helical backbone" holds domains 2 and 3
   both chains are homologous; the inter-chain arrangement of domains 1 is similar to the intra-chain arrangement of domains 2 and 3
   automatically mapped to Pfam PF00148
