Protein: Nitrogenase iron-molybdenum protein, beta chain from Azotobacter vinelandii [TaxId: 354]

Lineage:

1. Root: scop
2. Class: Alpha and beta proteins (a/b) [51349]
   Mainly parallel beta sheets (beta-alpha-beta units)
3. Fold: Chelatase-like [53799]
   duplication: tandem repeat of two domains; 3 layers (a/b/a); parallel beta-sheet of 4 strands, order 2134
4. Superfamily: "Helical backbone" metal receptor [53807]
   contains a long alpha helical insertion in the interdomain linker
   uperfamily
5. Family: Nitrogenase iron-molybdenum protein [53816]
   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
6. Protein: Nitrogenase iron-molybdenum protein, beta chain [81401]
   both chains are homologous; the inter-chain arrangement of domains 1 is similar to the intra-chain arrangement of domains 2 and 3
7. Species: Azotobacter vinelandii [TaxId: 354] [81397]
