Lineage for d1g20a_ (1g20 A:)

  1. Root: SCOPe 2.05
  2. 1815291Class c: Alpha and beta proteins (a/b) [51349] (148 folds)
  3. 1878032Fold 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. 1878139Superfamily c.92.2: "Helical backbone" metal receptor [53807] (5 families) (S)
    contains a long alpha helical insertion in the interdomain linker
  5. 1878197Family 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
