Lineage for Family c.92.2.3: Nitrogenase iron-molybdenum protein

  1. Root: SCOP 1.63
  2. 235644Class c: Alpha and beta proteins (a/b) [51349] (117 folds)
  3. 250478Fold c.92: Chelatase-like [53799] (2 superfamilies)
    duplication: tandem repeat of two domains; 3 layers (a/b/a); parallel beta-sheet of 4 strands, order 2134
  4. 250499Superfamily c.92.2: "Helical backbone" metal receptor [53807] (3 families) (S)
    contains a long alpha helical insertion in the interdomain linker
  5. 250520Family c.92.2.3: Nitrogenase iron-molybdenum protein [53816] (2 proteins)
    contains three domains of this fold; "Helical backbone" holds domains 2 and 3
    both chains are homologous; the interchain arrangment of domains 1 is similar to the intrachain arrangement of domains 2 and 3
